Zignal is a zero-dependency image processing library

Core Math: Matrices (SMatrix, Matrix, SVD), PCA, ND Geometry (SIMD Points, affine/projective transforms, convex hull), Statistics, Optimization.

Computer Vision: Feature detection and matching (FAST, ORB), Edge detection (Shen-Castan), Hough Transform, Feature Distribution Matching (style transfer).

Image Processing: Spatial transforms (resize, crop, rotate), morphology, convolution filters (blur, sharpen), thresholding, advanced Color Spaces (Lab, Oklab, Oklch, Xyb, Lms, etc.), Perlin noise generation.

I/O & Graphics: Pure-Zig PNG/JPEG codecs, Canvas API (antialiasing, Bézier curves), Bitmap/PCF Fonts, Colormaps, Terminal graphics (Kitty/Sixel).

Platform Support: Native Zig, first-class Python bindings, and WASM compilation for the web.

neat-looking zig image processing library with python bindings. Has a CLI that is currently pretty bare-bones.

Pretty impressive to have a library that does its own image decoding, font rendering, etc etc!
