1. A method for use in a processor for processing a compressed image, the method comprising:
receiving a compressed image of an original image, wherein the compressed image includes one or more compressed image sectors based on one or more original image sectors and each of the one or more original image sectors has a pixelization pattern,
wherein each of the one or more compressed image sectors is encoded using at least one of a delta function and a mapping function based on the pixelation pattern of the image sector to generate the one or more compressed image sectors; and
processing the one or more compressed image sectors of the compressed image to reconstitute the original image.
