Abstract
The present invention is a method and system for mixed resolution, multi-channel color image processing including compression, transmission and decompression. The color information is defined at a lower resolution since colors generally do not change at a high frequency and higher compression ratios may be obtained with the lower resolution. The edge information contains the commands switch between the foreground and background colors. The edge information occurs at high resolution and high frequency rates relative to the color information. The lower resolution color planes can be pixel replicated to the resolution of the edge information after compression and decompression for proper edge selection to occur. The resulting reconstructed image of foreground and background colors retains high detail.
