Research on the Face Recognition Based on Improved LBP Algorithm
LBP is defined as a texture description method demonstrated in a certain gray scale. There is a problem of insufficient data use in the classic LBP algorithm, so proposes a hierarchical LBP algorithm to solve the problem. In the new method, selects multiple threshold val-ues to serialize the images into LBP, then unions them and applies the improved HLBP algorithm to the face recognition. Based on YALE and ORL face databases, the experiments show that the recognition rate of HLBP algorithm is higher then that of classical LBP algorithm.
