Build Status License:MIT Coverage Status

This project is a computer vision library built on top of ndarray. This project is a work in progress. Basic image encoding/decoding and processing are currently implemented.

See the examples and tests for basic usage.


  • Conversions between Grayscale, RGB, HSV and CIEXYZ
  • Image convolutions and common kernels (box linear, gaussian, laplace)
  • Median filtering
  • Sobel operator
  • Canny Edge Detection
  • Histogram Equalisation
  • Thresholding (basic, mean, Otsu)
  • Encoding and decoding PPM (binary or plaintext)


Not a lot of work has been put towards performance yet but a rudimentary benchmarking project exists here for comparative benchmarks against other image processing libraries in rust.
