APPARATUS AND METHOD FOR DECODING AN IMAGE ENCODED WITH DISTRIBUTED VIDEO CODING

摘要

According to the present invention, an apparatus and method for decoding an image encoded with distributed video coding involve generating a plurality of candidate noise models for reflecting characteristics of a channel using information transmitted by an encoding apparatus and/or information generated or restored in the decoding apparatus, selecting, from among the plurality of candidate noise models, noise models appropriate for each of the predetermined channel coding units inputted to a channel code decoding unit using information generated or restored in the decoding apparatus and/or information transmitted by the encoding apparatus, and performing a channel decoding process. The decoding apparatus according to the present invention uses noise models that are appropriate for each of the predetermined channel coding units, thereby reducing the volume of compressed data transmitted by the encoding apparatus to restore a WZ picture, and significantly improving data compression performance.
