Abstract
A source image (101) consisting of more than one type of image is efficiently compressed. The source image (101) is divided into regions, and each region is assigned to one image type. Separate images (105) based on each image type are constructed from those regions belonging to that image type. These separate images (105) are compressed using schemes optimized for the image type. Later these compressed images are decompressed and reassembled into a reproduction (108) of the original source image (101).
