Abstract

A new class of multiscale symmetry features provides a useful high level representation for color texture. These symmetry features are defined within and between color bands using complex moments computed from the output of a bank of orientation and scale selective filters. From this representation, wee derive a set of features which are invariant to rotation, scale, and illumination conditions. Experimental results are provided to show the performance of this set of features for texture classification and retrieval
