rten-imageproc

Library for pre and post-processing image data stored in matrices. It includes functionality for:

• Finding contours of objects in segmentation masks
• Working with axis-aligned and oriented bounding boxes / rectangles
• Simplifying polygons
• Simple drawing of shapes

The genesis of this library was a need in the ocrs OCR engine for a Rust implementation of a subset of the geometry and image processing functionality provided by libraries like OpenCV and Shapely in Python.
