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

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")

Python API

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. Install via the umbrella with pip install scitex[cv] to use as scitex.cv (Python) or scitex cv ... (CLI).
