Abstract

A novel color rendering algorithm for printing images with flesh tone content is addressed in this paper. Instead of rendering the whole image with one color rendering dictionary (CRD), two CRDs, a global CRD and a flesh tone CRD are employed to correct the image adaptively. First, the optimal CRD for flesh-tone is designed by densely sampling, in color space, the flesh tone region and selecting special Neugebauer primaries. Then, a given image is segmented into flesh-tone and non-flesh-tone regions. The flesh-tone region is corrected by utilizing the flesh-tone CRD while the remainder of the image is corrected by employing the global CRD. The resulting separation of cyan, magenta, yellow and black could be sent directly to printer or could be compressed and stored for later use. The quality of the flesh tone content in an image will be improved by using optimally designed CRD for flesh tone while the rest of the image is corrected by the global CRD.
