Cascaded directional binary pattern for CBIR
Megha Agarwal · 2016
Cascaded directional binary pattern (CDBP) using directional extrema pattern is proposed for content based image retrieval in this paper. It avoids the problems associated with standard local binary pattern as well as its many variants. The directional information (0°, 45°, 90° and 135°) along with color information is incorporated in the proposed feature. The feature provides a balanced combination of local and global feature such that fine directional information is not lost. It works on spatial domain so the image characteristics remain intact. Experiments are performed on benchmark image database and improved performance of the proposed feature is justified over many variants of related features i.e. local binary pattern.
