SYSTEM AND METHOD FOR CATEGORIZING AN IMAGE

摘要

A system and method for performing object or context-based categorization of an image is described. A descriptor for image regions, which is represented by a histogram of oriented uniform patterns, is described. The descriptor is compared to descriptors of other images to determine a similarity score that accounts for distinctiveness, reducing perceptual aliasing. Additionally, a kernel alignment process considers only the descriptors that are determined to be most informative.

1. A method of generating a descriptor for an image region comprising:
a) applying one or more oriented band-pass filters each generating a coefficient for a plurality of locations in the image region; b) assigning one of a plurality of uniform pattern representations to each coefficient; and c) generating, by a processor, for each band-pass filter a histogram representing the distribution of uniform patterns among the plurality of uniform pattern representations.
