Feature Congestion and Subband Entropy measures of visual clutter

Abstract

This MATLAB software implements two measures of visual clutter described in our Journal of Vision 2007 paper in the special issue on crowding. The remaining measure described in that paper, Edge Density, is only two lines of MATLAB code and is fully described in the paper, so we do not include that code here. To run this software, you will likely need to download an updated version of Simoncelli's Steerable Pyramid software, available here: http://www.cns.nyu.edu/~eero/steerpyr/
