While using traditional local directional pattern（ LDP） and its improved method to carry out face recognition

there exist two problems

one is feature extraction is confined to 3 × 3 neighborhood; another is regions of face image are treated equally for face recognition. An improved LDP is proposed to handle the problems. On one hand

multi-resolution analysis method is proposed. LDP is extended from 3 × 3 window pattern to multi-resolution window pattern; on the other hand

different degree of contribution blocking to face recognition is enhanced by using block weighted method. Two face image databases

Yale and Orl

are used for experiment

and experimental results show that the introduced scheme can improve effect of face recognition.
