Using differential color models in lossless RGB-images compression tasks

In the paper several methods of determination of optimal differential color model for RGB-images lossless compression task based on predictors use are considered. Such optimal differential model allows compression parameters to be improved. An algorithm for determination and using of differential color model with integer coefficients is shown. Experiments have shown that using of the proposed differential color models allows compression rate of images to be increased approximately for 4,5 %.
