Abstract

A method for optimized image similarity measurement based on fusion of image descriptors is introduced. Descriptors of every kind can be used. The method is based on the nonparametric WaldWolfowitz (WW) statistical test, and the corresponding similarity measure, which is very well suited for that purpose. A simple addition of the above WW based similarity measures is the fusion rule proposed here. Experimental results in image retrieval task are very promising.
