Viola-Jones' Haarcascade visualisation

This is an unusual visualisation of haarcascades. Often, only haarcascade features are drawn. This visualisation however, adds up all matching features in an image. Resulting in a sort of lense which shows the contrasts in the image that the algorithm picks up on most.

  • The visual_haarcascades binary (main.rs) uses V4L to capture webcam input and renders to a canvas.
  • test.rs binary is an ugly program that looks hard-coded for haarcascade_frontalface_alt2.xml and test.png. It renders the output to test-output.png.
  • The library is made for use with eg. Python through cffi. See eg. this repo
