Abstract
A method for improving lossless image compression by using multiple lossless image compression techniques and adapting the best one to each image. An RGB compressor receives an image file and splits the image into rectangular block types. Different digital image and/or sub-image (block) types are optimally compressed using a compression techniques particularly well-suited for the particular kind of image or block.
