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]
