    • 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.
    • 根据本发明,用分解视频编码编码的图像进行解码的装置和方法包括使用由编码装置发送的信息和/或在解码中产生或恢复的信息来生成用于反映信道特性的多个候选噪声模型 从多个候选噪声模型中选择适用于使用在解码装置中生成或恢复的信息和/或由编码装置发送的信息输入到信道码解码单元的每个预定信道编码单元的噪声模型, 并执行信道解码处理。 根据本发明的解码装置使用适合于每个预定信道编码单元的噪声模型,从而减少由编码装置发送的压缩数据的数量以恢复WZ图像,并显着提高数据压缩性能。
