The efficiency of perceptual coding in compressing color
images relies on the estimation of perceptual redundancy.
In this paper, a color image coder is proposed for perceptually
lossless image compression which shapes the coding
error as a part of perceptual redundancy. The perceptual
redundancy inherent in each pixel of a color image is
estimated in terms of a triple of values, one for each color
channel, as a detection threshold for distortion.
