More Information
Summary:Processing of at least one digital image includes performing first and second separable block transforms in first and second directions; modifying results of the second block transforms; and performing first and second separable inverse block transforms in the first and second directions on the modified results. Transform coefficients are re-used while performing at least one the transforms. The processing can be performed on 2-D signals such as still images and 3-D signals such as video.
