Abstract

A method and apparatus for ranking pixels in an image by degrees of saliency, including: defining ( 200, 210 ) a plurality of regions for each of a plurality of pixels in an image, where each of the regions for any one of the pixels at coordinates (x,y) has a different scale s, calculating ( 230 ) an entropy value for each of the regions, identifying ( 260 ) any of the regions as having a peak entropy value, weighting ( 270 ) the peak entropy value of each of the peak entropy regions by a weight value corresponding to a peak width estimate of the peak entropy value, and ranking ( 290 ) the regions by the weighted peak entropy values, thereby ranking the pixels. The invention can be included in a method and apparatus for image transmission, providing preferential transmission of salient portions of the image.
