Abstract

In this study, the proposed approach is based on extracting small fragments of face by Adaptive Window Positioning (AWP) procedure was used for attribute extraction, which efforts on the face image into 16 small fragments of size (16x16) such that it is big enough to include ample data about the style of the person and small enough to ensure a good identification achievement. positioning windows over the face image and clustering similar face image fragments into clusters – the codebook. Fragments are then collected separately to obtain two codebooks, primary and secondary. Once the codebooks are generated, each face samples are represented by as a probability distribution of the patterns in the codebook. Then represents the combination of codebook designs for each person such that the number of categories in each codebook differs as a task of the face image. Two faces are then matched by calculating the dimension between their respective codebooks. Experimental outcomes illustration face recognition using windowing technique with combination of codebook is more efficient than other. The highest average estimation proportion of 98.15% is got for 80 individuals’ of publicly available ORL dataset including differences in illumination, posing, and expressions.
