ACM Trans. Mathematical Software 32, 635–653 (2006) 12. : The CMU pose, illumination, and expression database. IEEE Trans. kr Abstract. In this paper, we present a robust real-time face detection algorithm. We improved the conventional face detection algorithms for three different steps. For preprocessing step, we revise the modified census transform to compensate the sensitivity to the change of pixel values. For face detection step, we propose difference of pyramid(DoP) images for fast face detection.

Recently, the idea of active differential imaging has been applied to illumination invariant face recognition[9][10][1][6] and significant advantages on face recognition performance are reported for faces under varying illuminations. Specific sensors which can perform differential imaging have been proposed[3][7]. However, despite its success in removing ambient illuminations for a still scene, the active differential imaging system is detrimentally affected by any motion of the subject in the field of view.

CFTFS finds a transformation which reduces the size of image and minimizes the variation on color thrown away the information on color. If there are large illumination changes but only small number of samples are available, then these methods can’t prevent a sharp decline on face recognition performance. Our propose method, color face tensor factorization and slicing (CFTFS), solves these problem by conserving the color information and the spatial structure of original color face image ensemble.
