## How the System Works

The AutoAttendance system operates in three main phases:

### Phase 1: Data Collection
- Operator starts the data collection mode
- System captures 80-100 face samples of a person from various angles
- Samples are automatically saved to the database

### Phase 2: Model Training (Registration)
- System loads all collected face samples
- InsightFace deep learning model converts each face into a numeric vector (embedding)
- Embeddings are stored in SQLite database
- **Note**: The deep model is pre-trained; this phase registers new people into the system

### Phase 3: Live Recognition
- Camera feed is processed in real-time
- System detects faces in each frame
- For each detected face:
  - Generates an embedding using InsightFace
  - Compares against all stored embeddings using cosine distance
  - If distance ≤ threshold → **Known Person** (attendance marked)
  - If distance > threshold → **Unknown Person** (alert sent)
- Anti-spoofing check verifies face is real (not photo/screen)
- Attendance is automatically recorded in database

### Why This Approach Works

Traditional face recognition systems train a classifier from scratch, requiring thousands of labeled examples. AutoAttendance uses **embedding-based recognition**, where:

1. A pre-trained deep model extracts face features
2. Similar faces produce similar embeddings
3. Simple distance metrics (cosine distance) determine matches
4. New people can be added with just 80-100 samples
5. System is fast, scalable, and requires minimal training data

- **0.40-0.50**: Balanced (recommended)
- **0.50-0.60**: Lenient (more false accepts)

**When to adjust:**
- Too many unknowns → Lower threshold (0.40)
- Too many false recognitions → Raise threshold (0.50)

#### CAMERA_ID
If camera doesn't work:
- Windows: Try 0, 1, 2, 3
- Linux: Check `/dev/video*`
- Mac: Usually 0

#### FRAME_PROCESS_INTERVAL
- Lower (2-3): Faster recognition, higher CPU
- Higher (8-10): Lower CPU, slower response

---

## Troubleshooting

### Issue: Camera Not Found

**Solution:**
```python
# Edit config.py
CAMERA_ID = 1  # Try different numbers
```

**Windows - Using Device Manager:**
1. Open Device Manager
2. Find camera under "Imaging devices"
3. Right-click → Properties → Note the Device ID
4. Try camera IDs: 0, 1, 2, 3

### Issue: Poor Recognition Accuracy

**Causes & Solutions:**

1. **Not Enough Training Samples**
   - Collect at least 100 samples per person
   - Vary angles, lighting, distances

2. **Threshold Too High**
   - Lower `RECOGNITION_THRESHOLD` to 0.40

3. **Poor Lighting**
   - Improve camera lighting
   - Use natural light when possible

4. **Spoofed Face Detected**
   - User must present real face
   - Increase `SPOOF_THRESHOLD` slightly

### Issue: System Runs Slowly

**Causes & Solutions:**

1. **Too Many Frames Being Processed**
   - Increase `FRAME_PROCESS_INTERVAL` to 8-10

2. **High Resolution**
   - Reduce `FRAME_WIDTH` and `FRAME_HEIGHT` to 480p

3. **Multiple Faces in Frame**
   - Set `INSIGHTFACE_MAX_FACES = 1`
   - Ensure only one person at camera

4. **Insufficient RAM**
   - Close other applications
   - Upgrade system RAM if possible

### Issue: Unknown Emails Not Sending

**Check:**
1. Email address is valid
2. Gmail 2FA is enabled
3. App-specific password is set correctly
4. Internet connection is working

**Test Email:**
```bash
python -c "from email_notification import EmailNotification; EmailNotification().send_test_email()"
```

### Issue: Database Corruption

**Solution:**
```bash
# Backup current database
copy models/attendance.sqlite3 models/attendance.sqlite3.backup

# Delete corrupted database
del models/attendance.sqlite3

# Retrain model
python cli.py train
```

# AutoAttendance Project Architecture

## 1. Purpose

AutoAttendance is a face-recognition attendance system with two operating modes:

- a desktop real-time attendance application that uses a webcam to recognize people and mark them present
- a lightweight web dashboard and API that show attendance and registration data from the same database

The project is designed for day-to-day use by an operator, while also being structured clearly enough for academic review, prototyping, and further research.

## 2. What The System Does

At a high level, the system:

1. collects face images for each person
2. converts those images into face embeddings using a pretrained InsightFace model
3. stores the embeddings in SQLite
4. runs live recognition from a webcam
5. checks whether the detected face looks real or spoofed
6. records attendance for known people
7. exposes attendance data through exported files and a web dashboard

## 3. High-Level Architecture

## 4. Core Design Idea

This project is built around **embedding-based face recognition**.

That means the system does not train a face classifier from scratch. Instead, it uses a pretrained deep model to convert each face into a numeric vector called an embedding. During recognition, the system compares a new face embedding against the stored embeddings of registered people and finds the closest match.

This is the most important architectural idea in the project.

## 5. Main Subsystems

### 5.1 Configuration Layer

File: `config.py`

This file centralizes runtime settings such as:

- camera device and frame size
- processing interval for recognition
- InsightFace model configuration
- recognition threshold
- database and data directory paths
- anti-spoofing threshold

Important active settings:

- `INSIGHTFACE_MODEL_NAME = 'buffalo_l'`
- `INSIGHTFACE_PROVIDERS = ['CPUExecutionProvider']`
- `RECOGNITION_THRESHOLD = 0.45`
- `DATABASE_PATH = 'models/attendance.sqlite3'`
- `FRAME_PROCESS_INTERVAL = 5`

Architecturally, this file acts as the control panel for the entire system.

### 5.2 Data Collection Subsystem

File: `data_collection.py`

Purpose:

- collect face samples from the webcam
- save them under `data/faces/<person_name>/`
- guide the operator to capture different face angles

How it works:

1. the operator enters one or more names
2. the camera opens
3. the operator presses `c` to capture face samples
4. cropped face images are stored in that person's folder

This stage is the enrollment input stage of the system.

### 5.3 Registration / Training Subsystem

File: `train_model.py`

Purpose:

- process collected face images
- extract embeddings using InsightFace
- save the embeddings into SQLite

Important note:

This stage is called "training" in the script name, but in the current architecture it is closer to **registration** than full model training. The deep model itself is pretrained. What changes over time is the set of stored person embeddings.

### 5.4 Recognition Engine

File: `face_recognition.py`

This is the core machine-learning module.

Responsibilities:

- load the pretrained InsightFace `FaceAnalysis` app
- detect faces in incoming frames
- produce normalized face embeddings
- compare each new embedding with stored embeddings
- classify the face as known or unknown based on cosine distance

Recognition logic:

1. detect faces in the frame
2. compute an embedding for each face
3. compare the embedding with all stored embeddings
4. choose the best match by highest cosine similarity
5. convert similarity to distance using `1 - similarity`
6. accept the match only if distance is below the configured threshold

So the recognition path is:

```text
frame -> face detection -> embedding -> similarity search -> threshold decision
```

### 5.5 Anti-Spoofing Subsystem

File: `anti_spoofing.py`

Purpose:

- reduce false acceptance from printed photos or screen displays

Current method:

- Laplacian texture variance
- grayscale contrast
- high-frequency energy
- color variation

These features are combined into a liveness score. If the score is above `SPOOF_THRESHOLD`, the face is treated as real.

Research note:

This is a **heuristic passive liveness module**, not a learned anti-spoofing network. It is useful as a lightweight safety layer, but it should not be treated as a state-of-the-art spoof defense.

### 5.6 Live Attendance Runtime

File: `main.py`

Purpose:

- run the webcam-driven attendance workflow in real time

Responsibilities:

- initialize the camera
- load registered embeddings
- process frames continuously
- run recognition every `FRAME_PROCESS_INTERVAL` frames
- run liveness checks on face crops
- mark attendance for known faces
- show results visually in the camera window
- play alerts for unknown or spoofed detections
- export the final report when the session ends

This is the primary operational application of the project.

### 5.7 Attendance Management Subsystem

File: `attendance_manager.py`

Purpose:

- maintain daily attendance state
- prevent duplicate attendance entries
- write records to SQLite
- generate operator-friendly output files

Outputs:

- `attendance.log`
- `data/attendance/attendance.xlsx`
- `data/attendance/attendance_YYYY-MM-DD.csv`

This module acts as the bridge between recognition events and administrative reporting.

### 5.8 Data Persistence Subsystem

File: `database.py`

Purpose:

- provide SQLite-backed storage for the whole system

Main tables:

- `students`
- `face_embeddings`
- `attendance`
- `alerts`

This database is the single source of truth used by both the desktop application and the web API.

### 5.9 Dashboard and API Subsystem

File: `api.py`

Purpose:

- expose current attendance information through a FastAPI application
- provide a built-in dashboard page

Endpoints:

- `/` : HTML dashboard
- `/api/summary` : summary counts
- `/api/students` : student records
- `/api/attendance` : attendance records
- `/api/alerts` : alert records

This subsystem is read-oriented. It visualizes and serves the data already generated by the desktop runtime and registration pipeline.

## 6. End-To-End Operational Workflow

### Stage 1: Setup

Script:

```powershell
python setup.py
```

What it does:

- checks dependencies
- creates required directories
- prepares `.env`
- tests the camera

### Stage 2: Collect Face Samples

Script:

```powershell
python data_collection.py
```

Output:

- multiple cropped face images per person
- stored under `data/faces/<person_name>/`

### Stage 3: Register Embeddings

Script:

```powershell
python train_model.py
```

Output:

- people inserted or updated in SQLite
- embeddings stored in `models/attendance.sqlite3`

### Stage 4: Run Real-Time Attendance

Script:

```powershell
python main.py
```

Runtime behavior:

- webcam starts
- faces are detected
- known faces are matched and marked present
- unknown faces trigger visual and audio alerts
- spoof-like faces are rejected

### Stage 5: View Results

Desktop outputs:

- Excel file
- CSV daily export
- text log

Web dashboard:

```powershell
uvicorn api:app --reload
```

Open:

```text
http://127.0.0.1:8000
```

  -> data/faces/<person_name>/
```

### 7.2 Registration Data Flow

```text
Saved face images
  -> face_recognition.py
  -> InsightFace embedding extraction
  -> AttendanceDatabase.upsert_student()
  -> AttendanceDatabase.add_embedding()
  -> models/attendance.sqlite3
```

### 7.3 Attendance Data Flow

```text
Live camera frame
  -> main.py
  -> face_recognition.recognize_frame()
  -> best embedding match
  -> anti_spoofing.is_liveness_detected()
  -> attendance_manager.mark_attendance()
  -> database attendance table
  -> Excel / CSV / log output
```

### 7.4 Dashboard Data Flow

```text
SQLite database
  -> AttendanceDatabase queries
  -> FastAPI endpoints
  -> HTML dashboard and JSON API
```

## 8. Database Architecture

The database file is:

```text
models/attendance.sqlite3
```

### 8.1 students

Stores identity-level information.

Typical fields:

- `id`
- `name`
- `external_id`
- `department`
- `email`
- `phone`
- `status`
- `created_at`

### 8.2 face_embeddings

Stores one or more embeddings for each student.

Typical fields:

- `id`
- `student_id`
- `embedding`
- `embedding_dim`
- `image_path`
- `model_name`
- `quality_score`
- `created_at`

This design allows multiple face samples per student, which is useful for better recognition robustness across pose and lighting changes.

### 8.3 attendance

Stores daily attendance events.

Typical fields:

- `id`
- `student_id`
- `student_name`
- `date`
- `time`
- `status`
- `confidence`
- `camera_id`
- `created_at`

The current schema enforces:

```text
UNIQUE(student_name, date)
```

So one person is recorded at most once per day.

### 8.4 alerts

Stores security or anomaly alerts.

Typical fields:

- `id`
- `alert_type`
- `message`
- `image_path`
- `created_at`

## 9. Folder Structure

```text
AutoAttendance/
├── api.py
├── main.py
├── config.py
├── database.py
├── face_recognition.py
├── anti_spoofing.py
├── attendance_manager.py
├── data_collection.py
├── train_model.py
├── setup.py
├── email_notification.py
├── face_detection.py
├── data/
│   ├── attendance/
│   ├── faces/
│   ├── training/
│   └── unknown_faces/
├── models/
│   └── attendance.sqlite3
└── Reportformat/
```

### Folder meanings

- `data/faces/` contains enrolled face images
- `data/attendance/` contains generated attendance reports
- `data/training/` exists for compatibility and project organization
- `data/unknown_faces/` is reserved for unknown-person related handling
- `models/` stores the SQLite database
- `Reportformat/` contains report-writing assets and is separate from the runtime system

## 10. File Responsibility Map

### Runtime-critical files

- `main.py` - real-time attendance loop
- `face_recognition.py` - detection, embeddings, matching
- `anti_spoofing.py` - liveness heuristics
- `attendance_manager.py` - record management and exports
- `database.py` - persistence layer
- `config.py` - global settings

### Enrollment and preparation files

- `data_collection.py` - collect face images
- `train_model.py` - register embeddings
- `setup.py` - environment bootstrap

### Monitoring files

- `api.py` - web dashboard and JSON API

### Optional or legacy-adjacent files

- `face_detection.py` - Haar-cascade helper module, not the main active recognition path
- `email_notification.py` - email utility module, currently not wired into the main runtime flow

## 11. User View Of The System

A normal operator can understand the project in four steps:

1. collect face samples for each person
2. register those people into the system
3. run the camera-based attendance app
4. view attendance in reports or the dashboard

From a user perspective, the desktop app is the main tool and the dashboard is the reporting interface.

## 12. Researcher View Of The System

A researcher should understand the project through these architectural properties:

- the system uses a pretrained deep face model rather than training a new classifier
- recognition is embedding-based and threshold-driven
- the database stores multiple embeddings per identity
- attendance is event-based and deduplicated per day
- anti-spoofing is heuristic, lightweight, and passive
- the dashboard is a thin read layer over operational data

This makes the system suitable for:

- applied computer vision coursework
- prototyping attendance automation
- studying threshold-based recognition behavior
- extending toward stronger liveness detection or multi-camera deployments

## 13. Strengths Of The Current Architecture

- simple end-to-end workflow
- clear separation between capture, recognition, storage, and presentation
- one shared database for both the desktop app and web dashboard
- multiple embeddings per person for stronger matching robustness
- easy to extend because modules are already separated by responsibility

## 14. Current Limitations

These limitations are important for both users and researchers:

- anti-spoofing is heuristic and not highly robust against advanced attacks
- matching currently appears to use a linear scan over stored embeddings, which is fine for small deployments but not ideal at large scale
- some older documentation still describes an LBPH/Haar-centered design, while the live code now uses InsightFace plus SQLite
- `RECOGNITION_MODEL_PATH = 'models/face_recognizer.yml'` remains in configuration even though the active recognition path is database-based
- email notification utilities exist but are not integrated into the live attendance workflow

## 15. Conceptual Architecture Summary

In one sentence:

> AutoAttendance is an embedding-based face-recognition attendance platform in which enrollment images are converted into stored face embeddings, live camera frames are matched against those embeddings, attendance is written into SQLite, and results are exposed through exported reports and a FastAPI dashboard.

## 16. Minimal Architecture Summary For Presentation

If you need a short explanation for a user, teacher, or report:

```text
The system first collects face images for each student, then converts those
images into numerical face embeddings using a pretrained InsightFace model.
During live attendance, each webcam frame is analyzed, matched against the
stored embeddings, checked for basic liveness, and then recorded in a SQLite
database. The same database powers exported attendance reports and a web
dashboard.
```

## 17. Suggested Future Improvements

- replace heuristic anti-spoofing with a learned liveness model
- store unknown-face snapshots in `data/unknown_faces/`
- integrate `alerts` table writes directly from the live runtime
- connect `email_notification.py` into attendance and alert events
- add student metadata management through API endpoints
- support multi-camera deployments
- add ANN or vector indexing if the number of registered people grows large

## 18. Important Reality Check

Some files in the repository still reflect an older architecture based on LBPH and Haar cascades. The current live code path is different:

- main recognition is handled by `face_recognition.py` using InsightFace
- long-term storage is handled by SQLite in `models/attendance.sqlite3`
- the dashboard reads from the same SQLite store

So this document describes the **actual active architecture in code**, not just the original intended design.

FRAME_WIDTH=640
FRAME_HEIGHT=480
FPS=30

# Face Recognition
RECOGNITION_THRESHOLD=0.6     # Lower = stricter matching

# Anti-Spoofing
SPOOF_THRESHOLD=0.5           # Lower = stricter spoofing detection

# Email Alerts
ENABLE_EMAIL_NOTIFICATIONS=False

# 📊 How It Works

## Three-Phase System

### 1️⃣ Data Collection
- Collect 80-100 face samples per person
- Various angles and lighting conditions
- Automatic storage in SQLite

### 2️⃣ Model Training
- InsightFace converts faces → embeddings
- Embeddings stored in database
- Model is pre-trained (no retraining needed)

### 3️⃣ Live Recognition
- Real-time face detection
- Embedding comparison (cosine distance)
- Anti-spoofing verification
- Automatic attendance marking

## Why It's Effective

- ✅ Pre-trained model = No deep learning required
- ✅ Embedding-based = Minimal training data needed
- ✅ Cosine distance = Fast and accurate matching
- ✅ Scalable = Add new people anytime

# Face Detection Not Working - Troubleshooting Guide

## Quick Fix Checklist

### Step 1: Train Face Embeddings (CRITICAL)
If you haven't done this yet, faces won't be recognized. Run:

```bash
python train_model.py
```

**Expected output:**
```
Processing karim: 100 images
  karim: 100/100 images registered
Processing masud: 50 images
Processing rudo: 40 images
Processing soumitra: 60 images
Registration completed successfully!
Total people registered: 4
Total embeddings registered: 250
```

### Step 2: Restart the Web UI
After training, restart the web UI:

```bash
python run_web_ui.py
```

### Step 3: Check Dashboard
- Open http://localhost:5000
- Check if "Face Embeddings" count shows > 0
- If it shows 0, embeddings didn't load properly

### Step 4: Test Face Detection
Click **"Start Attendance"** button:
- Camera should open
- **Green box** = Known person (attendance marked)
- **Red box** = Unknown person (not in database)
- **Orange box** = Spoofing detected (printed photo or screen)
- **No boxes** = No faces detected (see troubleshooting below)

---

## Troubleshooting If Faces Still Not Detected

### Issue 1: No Face Boxes Appear at All

**Possible Causes:**

1. **Camera Problem**
   - Is camera facing you?
   - Is there enough light?
   - Try moving closer to camera (30-60cm away)

2. **InsightFace Model Not Loaded**
   - Check logs: `logs/attendance_*.log`
   - Look for errors mentioning InsightFace or ONNX

3. **Embeddings Not Trained**
   - Check if database has embeddings:
     ```bash
     python -c "from database import AttendanceDatabase; db = AttendanceDatabase(); print(f'Embeddings: {db.get_total_embeddings()}')"
     ```
   - If shows 0, run `python train_model.py`

### Issue 2: Faces Detected But Not Recognized (Always "Unknown")

**Possible Causes:**

1. **Training Images Are Poor Quality**
   - Use images with:
     - Clear, frontal face view
     - Good lighting
     - Neutral expression
   - Remove blurry or side-view images

2. **Recognition Threshold Too Strict**
   - Edit `config.py`:
     ```python
     RECOGNITION_THRESHOLD = 0.50  # Increase from 0.45 for more lenient matching
     ```
   - Restart web UI
   - Run `python train_model.py` again

3. **Not Enough Training Images**
   - Retrain with more images (100+ per person recommended)
   - Delete `models/attendance.sqlite3`
   - Run `python train_model.py`

### Issue 3: Model Loading Errors

**Check Debug Output:**

1. Open new terminal and run:
   ```bash
   python -c "from face_recognition import FaceRecognitionModule; r = FaceRecognitionModule(); r.load_model()"
   ```

2. Look for errors about:
   - InsightFace import failures → Install: `pip install insightface onnx onnxruntime`
   - Model download failures → Check internet connection
   - ONNX runtime errors → Install correct version: `pip install onnxruntime`

---

## Key Components

### 1. Training Pipeline
```
Raw Images (data/faces/person_name/*.jpg)
    ↓
InsightFace Detector (detects face in image)
    ↓
Face Embedding (512-dimensional vector)
    ↓
SQLite Database (models/attendance.sqlite3)
```

### 2. Recognition Pipeline (Real-time)
```
Camera Frame
    ↓
InsightFace Detector (detects faces in frame)
    ↓
Face Embedding for each detected face
    ↓
Compare with Database Embeddings
    ↓
Display Result (Green/Red/Orange box)
```

### 3. Anti-Spoofing Check
- Analyzes texture (Difference of Gaussians method)
- Detects printed photos and screen replays
- Must pass before attendance is marked

---

## Verify Everything Works

Run this Python script to diagnose:

```python
from database import AttendanceDatabase
from face_recognition import FaceRecognitionModule
import cv2

# Check embeddings
db = AttendanceDatabase()
embeddings = db.get_total_embeddings()
print(f"✓ Database embeddings: {embeddings}")

# Check model
rec = FaceRecognitionModule()
rec.load_model()
print(f"✓ Model loaded, known faces: {rec.label_count}")

# Check camera
cap = cv2.VideoCapture(0)
ret, frame = cap.read()
if ret:
    faces = rec.detect_faces(frame)
    print(f"✓ Camera works, detected {len(faces)} faces")
cap.release()
```

---

## Still Having Issues?

1. **Check logs:**
   ```bash
   tail -50 logs/attendance_202605.log
   ```

2. **Look for these error patterns:**
   - "No face embeddings found" → Run `python train_model.py`
   - "Failed to load model" → Check InsightFace installation
   - "Cannot open camera" → Check CAMERA_ID in config.py
   - "Error processing frame" → Check anti_spoofing module

3. **Common fixes:**
   - Delete `models/attendance.sqlite3` and retrain
   - Update InsightFace: `pip install --upgrade insightface`
   - Verify camera ID: Check System Information for correct device

---

## How It Should Look

When working correctly:
- ✓ Dashboard shows count of registered faces
- ✓ Camera feed displays in real-time
- ✓ Faces show colored boxes (green = known, red = unknown)
- ✓ Names appear above faces
- ✓ Attendance records update in real-time

## Detailed Compilation Explanation

### What Happens When You Run pdflatex

First run:
```
pdflatex main.tex
↓
Reads main.tex
↓
Processes \include and \input commands
↓
Reads all chapter files
↓
Builds Table of Contents (stored in .toc file)
↓
Generates main.pdf (with ??? for TOC page numbers)
```

Second run:
```
pdflatex main.tex
↓
Uses .toc file from first run
↓
Generates correct page numbers in TOC
↓
Generates final main.pdf
```

This is why you need to run `pdflatex` twice!

---

## Troubleshooting by Error Message

### Error: "command not found: pdflatex"
**Cause:** LaTeX not installed or not in PATH
**Solution:** 
- Install appropriate LaTeX distribution (see above)
- Restart terminal/command prompt after installation

### Error: "File 'chapter1.tex' not found"
**Cause:** Running pdflatex from wrong directory
**Solution:**
- Ensure you're in the AutoAttendance directory
- Check file names match exactly (case-sensitive on Linux/Mac)

### Error: "Undefined control sequence"
**Cause:** Missing LaTeX package or typo
**Solution:**
- Run pdflatex again (may auto-install on MiKTeX)
- Check for typos in main.tex or chapter files

### Warning: "Underfull hbox"
**Cause:** Text fitting issues (usually harmless)
**Solution:** Usually safe to ignore, or adjust text

### Compilation Takes Very Long
**Cause:** First run with MiKTeX downloading packages
**Solution:** This is normal; subsequent runs are faster

---

## Performance Tips

### Fast Compilation
1. Use `-interaction=nonstopmode` flag:
   ```bash
   pdflatex -interaction=nonstopmode main.tex
   ```

2. Clean temporary files before compiling:
   ```bash
   rm -f *.aux *.log *.out *.toc  # Linux/Mac
   del *.aux *.log *.out *.toc    # Windows
   ```

3. Skip viewing PDF during compilation

### Faster Development Workflow
1. Comment out non-essential chapters in main.tex during editing
2. Use `\documentclass[draft]{book}` for draft mode
3. Disable TOC generation during editing

---

## Verification Checklist

- [ ] `main.pdf` file exists
- [ ] PDF file size > 500KB
- [ ] PDF opens in reader without errors
- [ ] Title page displays correctly
- [ ] Table of Contents has page numbers
- [ ] All chapters are included
- [ ] Equations render correctly
- [ ] Tables display properly

---

# AutoAttendance Presentation Slides

This Markdown file is a 15-slide presentation outline for the AutoAttendance project. It is based on the current codebase, the project report, and the active implementation in the repository.

## Slide 1. Title Slide
- **Project title:** AutoAttendance
- **Subtitle:** Real-Time Face Recognition Based Automated Attendance System with Passive Liveness Detection
- **Presenter:** Md. Mahfujul Karim Sheikh
- **Course:** CSE 4206, Neural Network Lab
- **Institution:** Northern University of Business and Technology Khulna

## Slide 2. Problem Statement
- Manual attendance takes time and interrupts class or work.
- Paper registers and roll calls are prone to proxy attendance and recording errors.
- A better system should be contactless, fast, and easier to manage.
- AutoAttendance addresses these issues using webcam-based face recognition.

## Slide 3. Project Goal
- Capture and register face data for each person.
- Recognize known faces from a live camera stream.
- Mark attendance automatically and prevent duplicates.
- Store data locally and expose it through a dashboard.
- Add a lightweight liveness check to reduce spoofing.

## Slide 4. System Overview
- The project has two main runtime parts.
- Desktop app: `main.py` for live camera attendance.
- Web app: `api.py` for dashboard and summary data.
- Database: `models/attendance.sqlite3` stores students, embeddings, attendance, and alerts.

## Slide 5. Project Architecture
- `data_collection.py` collects face samples from the webcam.
- `train_model.py` registers embeddings from collected images.
- `face_recognition.py` performs detection and matching.
- `anti_spoofing.py` checks passive liveness.
- `attendance_manager.py` writes attendance to SQLite, Excel, CSV, and logs.

## Slide 6. Technology Stack
- Python is the main language.
- OpenCV handles camera input and display.
- InsightFace provides pretrained face analysis and embeddings.
- SQLite stores all persistent data locally.
- FastAPI powers the lightweight dashboard and API.
- Pandas and OpenPyXL support reporting exports.

## Slide 7. Face Data Collection
- The operator enters one or more person names.
- The webcam opens and face images are captured manually.
- The script recommends varied angles and lighting for better recognition.
- Images are saved under `data/faces/<person_name>/`.
- The default collection target is 80 samples per person.

## Slide 8. Registration and Model Setup
- `train_model.py` does not train a new deep model from scratch.
- It registers embeddings extracted from collected face images.
- Each person is inserted or updated in SQLite.
- The project uses a pretrained InsightFace model named `buffalo_l`.
- This makes enrollment faster than retraining a classic LBPH model.

## Slide 9. Recognition Workflow
- A frame is captured from the webcam.
- InsightFace detects faces and extracts normalized embeddings.
- The embedding is compared with stored embeddings in SQLite.
- Matching uses cosine similarity converted to cosine distance.
- The configured recognition threshold is `0.45`.

## Slide 10. Attendance Logic
- Known faces are marked present automatically.
- Attendance is stored only once per person per day.
- Duplicate prevention is enforced both in memory and in SQLite.
- The system writes to `attendance.log` and `data/attendance/attendance.xlsx`.
- A CSV daily report can also be exported.

## Slide 11. Anti-Spoofing
- The project uses passive liveness detection.
- It checks texture variance, contrast, frequency energy, and color variation.
- A weighted score determines whether a face looks real.
- The liveness threshold is `0.35`.
- This helps block simple printed-photo or screen-based spoofing.

## Slide 12. Web Dashboard and API
- `api.py` serves a dashboard in the browser.
- It shows total students, total embeddings, and present count for today.
- It lists recent attendance records with confidence values.
- It includes API endpoints for summary, students, attendance, and alerts.
- The dashboard uses a clean, responsive HTML interface.

## Slide 13. Data and Outputs
- Registered students are stored in the `students` table.
- Face embeddings are stored in the `face_embeddings` table.
- Attendance events are stored in the `attendance` table.
- Security and unknown-face events are stored in the `alerts` table.
- Main outputs include SQLite data, Excel files, CSV reports, and logs.

## Slide 14. Current Project Status
- The repository contains a complete working prototype.
- The report documents two enrolled people: `karim` and `soumitra`.
- The project report also documents 200 stored face embeddings.
- Example attendance data already exists in `data/attendance/`.
- The system runs on CPU using `CPUExecutionProvider`.

## Slide 15. Conclusion and Future Work
- AutoAttendance shows a practical end-to-end attendance workflow.
- It combines recognition, liveness checking, storage, and reporting.
- The most useful future improvements are stronger liveness detection, multi-face support, authentication for the dashboard, and encrypted biometric storage.
- The project is a solid base for a real deployment or further research.
