摘要：
This paper presents research on importance of color information in face verification system. Four most popular color spaces where used: RGB, YIQ, YCbCr, luminance and compared using four types of discriminant classifiers. Experiments conducted on facial databases with complex background, different poses and light condition show that color information can improve the verification accuracy compared to the traditionally used luminance information. To achieve the best performance we recommend to use multi frames verification encoded to YIQ color space.
