Abstract
An image is divided into a plurality of blocks and a first transform is applied to each of the blocks to generate a plurality of first transformed blocks, wherein each of the first transformed blocks comprises a DC first transformed signal and a plurality of AC first transformed signals. A second transform is applied to the DC first transformed signals for all of the first transformed blocks to generate a plurality of second transformed signals. The second transformed signals are encoded and then the AC first transformed signals are encoded.
