imageproc is a Rust library providing a comprehensive suite of image processing operations built on top of the `image` crate. It includes a wide range of filters (Gaussian blur, bilateral, median, sharpen), geometric transformations (rotation, scaling, warping, projection), drawing primitives (lines, shapes, text with font rendering), feature detection (FAST corners, BRIEF descriptors, Hough lines, HoG, Haar-like features), contrast manipulation (histogram equalization, Otsu thresholding), morphology (dilation, erosion, structuring elements), distance transforms, template matching, seam carving, image hashing, and noise addition. The library is designed for performance with extensive use of `unsafe` code where justified, and provides both mutable and immutable API variants, as well as parallel execution via the `rayon` feature. It serves as a practical tool for computer vision and graphics editors, with a focus on correctness and reproducibility (regression tests against reference images). The crate is modular, with each major operation in its own file, and includes many examples demonstrating realistic workflows like edge detection, object matching, and text overlay. While not a research project, it implements classic computer vision algorithms with modern Rust idioms and is actively maintained with regular releases.
