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.

lib.rs:

Provides 2D geometry and image processing functions.

This includes:

• 2D vectors and related math
• 2D shapes and associated algorithms: [Point], [Line], [Rect], [RotatedRect], [Polygon]
• Rudimentary drawing functions
• Algorithms for finding the contours of connected components in an image ([find_contours])
• Algorithms for simplifying polygons and finding various kinds of shape that contain a polygon: [simplify_polygon], [min_area_rect], [convex_hull]
