Abstract
This paper considers different algorithms for solving the color constancy problem in the block DCT domain. New algorithms in this domain have been proposed by exploiting the advantage of smaller data size and the better chromatic separation of Y-Cb-Cr color space (as used in the JPEG standard) against the R-G-B color space of the spatial domain. These make them faster and less memory intensive compared to their equivalent ones in the spatial domain without any significant degradation of the quality of the results.
