Grayskull: A Minimalist, Dependency-Free Computer Vision Library for Embedded Systems

Summary

Grayskull is a minimalist, dependency-free computer vision library written in C99 specifically designed for resource-constrained embedded systems like microcontrollers, drones, and robotics. It focuses on grayscale image processing with modern algorithms that fit in just a few kilobytes of code. The library features a single-header design, integer-based operations, and includes essential computer vision functions such as image operations (copy, crop, resize), filtering (blur, edge detection, thresholding), morphology (erosion, dilation), geometry operations (connected components, perspective warp), and feature detection (FAST/ORB keypoints for object tracking).
