Research output: Contribution to journalConference articlepeer-review


The context of 24-bit true color image encoding is studied using searchless vs. search-based fractal compression techniques in a perceptually uniform color space. To account for the nonlinearity of the human visual perception, compression in the L a b uniform color space is proposed. In this color space, two pairs of colors with the same Euclidean distance metric are perceptually almost similar or different. Comparisons are presented both with regard to compression in the RGB and YIQ color spaces vs. the perceptually uniform L a b color space, as well as with regard to fractal color image compression in the L a b color space obtained by means of Jacquin's Iterated Transform Technique for 3-dimensional color.
