摘要： The present disclosure is directed to methods, systems, and apparatus for improved data compression. In one embodiment, a method is provided that separates image data by color channels and ordered bit planes. The method includes arranging bytes representing pixel values from a source image into corresponding color channels. Bits in each color channel are separated into a plurality of bit planes that are ordered based on significance. Then, the method may combine bits associated with adjacent pixel locations from common bit planes into new bytes. Once the image data is separated in this way, different compression processes are applied to data sets represented in the ordered bit planes.
