Abstract: In modern society,the use of face recognition technology in a variety of fields is increasing.Meanwhile,the problems of social security environment and international security are becoming more serious,thus face recognition is confronted with more severe challenges.Detection target and background are complex and dynamic in a complicated environment,so the traditional face recognition technology can not meet the growing demand.Therefore,in this paper,the traditional SIFT (Scale,Invariant,Feature,Transform) algorithm is optimized by clustering analysis method,and the object features are classified according to the principle of clustering analysis,so as to make the clustering results more in line with the set threshold and improve the matching efficiency.The results show that the improved SIFT algorithm can eliminate the interference of irrelevant books and realize the complete connection of image matching points.In order to verify the effectiveness of the improved SIFT algorithm, it is compared with the common algorithms based on several commonly-used databases,and the results show that the clustering algorithm SIFT is better than other algorithms in CASPEALG R1,CFP,MultiGPIE,and has better application effect and applicability.

Key words: Cluster analysis, Feature matching, SIFT algorithm
