A simple texture descriptor for texture retrieval

Texture feature extraction is an important part in content-based image retrieval system. This paper describes a simple and effective texture feature extraction algorithm. Previous work based on image decomposition techniques usually use mean and variance of each subband in decomposition domain to form texture descriptor. The proposed texture descriptor uses the variance information and the luminance property of the texture to form the descriptor. Experimental results on the Brodatz texture database show that the proposed descriptor can provide comparable retrieval performance with approximately only half the number of features used compared with previous work.
