Color Image Indexing by Combining Spatial Color and Texture Descriptors

Abstract

In this paper, we propose a technique for retrieving images using spatial color correlation and texture characteristics based on local fourier transform. As experimental results, while the proposed color descriptor includes by rar smaller feature vector over color correlogram, the proposed color descriptor improves 2.5%~13.21% precision rate, compared with color corelogram. In addition, we propose a another descriptor which combines the proposed color descriptor and texture characteristiecs based on local fourier transform. The combined method reduces size of feature vector as well as shows improved results over existing methods.
