About
Grayskull is a minimalist, dependency-free computer vision library written in C, specifically engineered for microcontrollers and other resource-constrained devices like drones and robotics. It focuses on grayscale image processing, providing a suite of modern and practical algorithms that fit within a few kilobytes of code. Key features include image operations such as copy, crop, resize (bilinear), and downsample, along with filtering capabilities like blur, Sobel edges, and various thresholding methods (global, Otsu, adaptive). The library also supports morphology operations (erosion, dilation), geometry functions like connected components and perspective warp, and advanced features like FAST/ORB keypoints for object tracking and LBP cascades for face and vehicle detection. Its single-header design, integer-based operations, and pure C99 implementation ensure no dynamic memory allocation or C++ dependencies, making it ideal for embedded vision projects.
