Face Recognition using Novel FSP Method

Abstract

Face recognition has become an actively researched area due to its applications like security systems, criminal identification, and credit card verification. Unfortunately, expressing face images mathematically is quite difficult because faces are complex visual stimuli. In recognition systems there is a problem of minimizing the dimensionality of extracted features from face images. This paper presents the work done on a face recognition system, which uses Hybrid Color space (HCS) and Principal Component Analysis (PCA) method, along with proposed Face Symmetry Property (FSP) for recognition of human face. Color provides useful information for face recognition system so a RCbCr hybrid color space has been proposed. Less computation increases the efficiency of any recognition system, thus computational cost has been reduced half by using an interesting and simple innovation FSP. In addition to FSP, PCA method is employed for improving the generalization capability. Experiments were conducted on 64x64 resolution using various criteria of recognition. Experiments using PCA with and without FSP are conducted. The proposed model which used PCA with FSP was named as PCA-FSP. When using PCA-FSP, the resolution of the images became 64x32. It was seen that the concept of FSP is very effective for reduction of computational cost, storage space, and system complexity. Performance comparison of the proposed system(PCA-FSP) was made with simple PCA. Results suggest that the proposed system shows satisfactory performance.
