Image Retrieval Technology Based on Color Similarity Matrix

Abstract

Somecolor quantization problems concerning quantization of a color image into a fewnumbers of colors are discussed. In the HSV color space that is the best visualidentity of people, H is uniform quantified, S and V is respectivelynon-uniform quantified.Aimed at the limitation of Euclidean distance failing to consider thesimilarity between colors in the process of retrieval, a color similaritymatrix is introduced. Experimental result shows this algorithm is of certainpracticability and the quantization effect is also comparatively ideal whenmaking similarity matching
