Abstract
In certain image analysis applications, it is desirable to compress the image while emphasizing a selected region of the image. The invention is a means for to allocating more bits, and thus better quality in the decoded image, to the selected region at the expense of other regions of the image. This allows efficient compression of the image for storage or transmission with those regions deemed to be important preserved at high quality and other regions stored with minimal quality to preserve the context of the image.
