This repository covers all formats of annotations for Object Detection and can easily convert from one form to another using the `cvannotate` Python package.

> **✨ v1.0.0 Stable Release** - Production-ready with comprehensive testing and CI/CD pipeline.

## Installation

### PyPI (Recommended)

Install the stable release from PyPI:
```bash
pip install cvannotate
```

### Development Version

For the latest development features:
```bash
pip install -i https://test.pypi.org/simple/ cvannotate
```

### Conda/Mamba

Create a conda environment and install:
```bash
# Create environment
conda create -n cvannotate python=3.11
conda activate cvannotate

# Install from PyPI
pip install cvannotate

# Or use environment file
conda env create -f environment.yml
```

### From Source

```bash
git clone https://github.com/Echo9k/cv-format-annotation-converters.git
cd cv-format-annotation-converters
pip install -e .
```

## Quick Start

### CLI Usage

```bash
# Convert YOLO to VOC format
cvannotate convert -i annotations.txt --from-format yolo -f voc -w 640 --height 480 -c classes.txt

# Convert VOC to COCO format  
cvannotate convert -i annotations.xml --from-format voc -f coco -c classes.txt

# Convert COCO to YOLO format
cvannotate convert -i annotations.json --from-format coco -f yolo -w 640 --height 480 -c classes.txt
```

### Python API

```python
from cvannotate import convert
from pathlib import Path

# Example 1: YOLO → VOC conversion
annotations = convert.read_annotation(
    Path("data/labels.txt"), 
    "yolo", 
    width=640, 
    height=480
)
convert.write_annotation(
    annotations, 
    Path("output/"), 
    "voc", 
    ["person", "car", "bicycle"]
)

# Example 2: Batch conversion
import os
from cvannotate.cli import main

# Convert entire directory
os.system("cvannotate convert -i dataset/labels/ --from-format yolo -f coco -c classes.txt")
```

## Common Use Cases

### Dataset Conversion for Training
```bash
# Convert YOLO dataset to COCO for frameworks like Detectron2
cvannotate convert -i train.txt --from-format yolo -f coco -w 640 --height 480 -c classes.txt

# Convert VOC XML files to YOLO for frameworks like YOLOv5/v8  
cvannotate convert -i annotations.xml --from-format voc -f yolo -w 416 --height 416 -c classes.txt
```

### Validation and Testing
```bash
# Convert predictions back to original format for evaluation
cvannotate convert -i predictions.json --from-format coco -f yolo -w 640 --height 480 -c classes.txt
```
