Texture image retrieval by combining local binary pattern and discontinuity binary pattern

Local binary pattern (LBP) is a nonparametric descriptor, which efficiently summarizes the local structures of images and has been very successful in image retrieval applications. In this paper, we propose a texture image retrieval technique which uses discontinuity binary pattern (DBP) along with the LBP. The DBP is formed by thresholding the absolute difference between the center pixel and its neighbors. This technique is applied to a database of 1180 sub-images from the twenty different classes of vistex database. Result shows that the proposed technique achieves good retrieval rate.
