A method and apparatus for processing an image is described. In one embodiment,
the method comprises: receiving a portion of an encoded version of a downsized
image and one or more encoded residual images, decoding the portion of the encoded
version of the downsized image to create a decoded portion of the downsized image,
decoding a portion of at least one or more encoded residual images, enlarging the
decoded portion of the portion of the downsized image, and combining the enlarged
and decoded portion of the downsized image with a first decoded residual image
to create a new image.
