An Extension to the Local Binary Patterns for Image Retrieval
Zhize Wu, Yu Xia, Shouhong Wan · Advanced Science and Technology Letters · 2014
In this paper, we propose an extension to the local binary patterns for image retrieval. We focus on the spatial distribution information in images, and present a spatial-distribution-information-enhanced local pattern for content-based image retrieval. Differing from traditional local patterns, we group those gray-level varying values according to three directions, and each group is then merged into a local spatial distribution pattern to represent the spatial distribution property of the image. Our preliminary experimental results on a real dataset demonstrate the effectiveness of our algorithm.
