ABSTRACT:
Color image information is encoded by grouping together adjacent pixels into blocks, determining which one of several templates each block most closely approximates, and encoding each block in accordance with the rules for a particular template. Data compression without loss of image quality results because the encoding rules for each template ignore irrelevant or duplicative information, thereby saving space for information that is important.
