Abstract
A method for compressing and reconstructing original picture data representative of a plurality of pixels. The method includes a partitioning step and a weighting step. In the partitioning step, the original picture data is partitioned into a plurality of input blocks, with each such input block comprising data representative of border pixels shared with adjacent input blocks and unshared interior pixels surrounded by the border pixels. In the weighting step, data representative of the border pixels is weighted in order to reduce distortions of the original picture data caused by subsequent steps of such method.
