Module Documentation

Computes a saliency map and gist, intended for use by machines.

See the DemoSaliency modute for more explanations about saliency and gist algorithms and for a demo output intended for human viewing.

What is returned depends on the selected output image resolution; it should always be grayscale, and can contain any of:

  • saliency map only
  • saliency + gist
  • saliency + feature maps
  • saliency + feature maps + gist
This module has no screenshots and no videos
