Image compression mismatch effect on color image based face recognition system
Face recognition (FR) for emerging applications such as face tagging for social networking, consumer products, and gamming utilize color images stored in distributed repositories. Such images are often in compressed format and of different dimensions. This compression mismatch problem may adversely affect the performance of the face recognition engine. In this paper, we present a comparative investigation of the image compression mismatch problem. Two commonly used color image based face recognition solutions are utilized. More than three thousand images of 341 subjects, typical of the problem, are collected from three public databases. The experimental results support the main thesis of the paper that recognition performance depends critically on the color image properties.
