Feature selection is an effective tool to improve the performance of content based image retrieval systems. This paper presents an effective moment weighting method according to image reconstruction and retrieval accuracyto reduce the dimensionality of moment-based features. Weighting algorithms are important group of feature selection schemes. Among features employed in content based image retrieval systems, orthogonal moments are shape features which have been used to distinguish objects.
