## Installation

```bash
pip install scitex-cv
```

## Architecture

```
scitex_cv/
├── __init__.py        ← public API (load, save, resize, blur, edge_detect, ...)
├── _io.py             ← image I/O wrappers (PIL / OpenCV backends)
├── _transform.py      ← geometric transforms (resize, crop, rotate)
├── _filters.py        ← blur, sharpen, edge-detect filters
└── _draw.py           ← annotation helpers (draw boxes, text, masks)
```

Thin, opinionated wrapper around PIL + OpenCV — every public name in
`__init__.py` re-exports from one of the four leaf modules above.

## Quick Start

```python
import scitex_cv as cv

img = cv.load("input.png")
img = cv.resize(img, scale=0.5)
img = cv.blur(img, ksize=5)
edges = cv.edge_detect(img, method="canny")
cv.save(edges, "edges.png")
```

## 1 Interfaces

<summary><strong>Python API</strong></summary>

<br>

```python
import scitex_cv as cv

# I/O
img = cv.load("input.png")
cv.save(img, "out.png")
gray = cv.to_gray(img); rgb = cv.to_rgb(img); bgr = cv.to_bgr(img)

# Transform
cv.resize(img, scale=0.5)
cv.rotate(img, angle=90)
cv.flip(img, direction="horizontal")
cv.crop(img, x=10, y=10, width=100, height=100)
cv.pad(img, top=10, bottom=10, left=10, right=10)

# Filters
cv.blur(img, ksize=5); cv.sharpen(img)
cv.edge_detect(img, method="canny")
cv.threshold(img, thresh=128); cv.denoise(img)

# Drawing
cv.rectangle(img, (5, 5), (30, 30), color=(0, 255, 0))
cv.circle(img, (50, 50), radius=10)
cv.line(img, (0, 0), (100, 100))
cv.arrow(img, (0, 0), (50, 50))
cv.text(img, "label", (10, 30))
cv.polylines(img, points=np.array([[0, 0], [100, 0], [100, 100]]))
```

## Status

Standalone fork of `scitex.cv`. Only deps are numpy + opencv-python.
The umbrella package's `scitex.cv` import path is preserved via a
`sys.modules`-alias bridge.

## Part of SciTeX

`scitex-cv` is part of [**SciTeX**](https://scitex.ai). Install via
the umbrella with `pip install scitex[cv]` to use as
`scitex.cv` (Python) or `scitex cv ...` (CLI).
