Image Retrieval Technique Using Local Binary Pattern ( LBP )

The increased need of content based image retrieval technique can be found in a number of different domains such as Data Mining, Education, Medical Imaging, Crime Prevention, Weather forecasting, Remote Sensing etc. An image retrieval system allows us to browse, search and retrieve the images. In early days because of very large image collections the manual annotation approach was more difficult. In order to overcome these difficulties content based image retrieval was introduced. This paper presents the content based image retrieval, using local binary pattern (LBP). The local binary pattern encodes the relationship between the referenced pixel and its surrounding neighbors by computing the gray-level difference. The objective of the proposed work is to retrieve the best images from the stored database that resemble the query image.
