ABSTRACT:
In a coding system, an input picture is split into regions with adaptive configurations to a reference picture, a selected region with precedence data is detected of its configuration and of its relative motion to a corresponding region of the reference picture, a prediction region is generated from the corresponding region of the reference picture and the relative motion, a difference region is determined between the selected region and the prediction region, and the precedence data, detected configuration, relative motion and difference ergion are coded. In a decoding system, a decoded prediction region is generated from a decoded relative motion and a corresponding region of a reference picture selected by a decoded precedence data, and a decoded difference region is added to the decoded prediction region to obtain a decoded picture region, which is configuration-corrected by a decoded configuratrion data, before synthesizing a plurality of decoded picture regions to obtain a synthesized picture region.
