摘要:【中文】本发明公开了两种图像编码解码方法。在其中一种图像编码解码方法中,通过将图像进行二值化处理,对图像进行比特平面的分层后,采用Context模型所构建的各像素的概率分布模型来对信源进行抽样编码,以提高图像编码的压缩率。在另一种图像编码解码方法中,在基于Context模型所建立的概率分布模型中加入禁止符号区,使得在对图像进行解码的时候,部分码字会落入禁止符号区,进而在对码字进行解码的过程中,判断码字是否落入禁止符号区,若落入则当前解码路径不可用,反之则保留当前解码路径,然后通过采用最大后验概率算法获得最终的解码结果,进而提高解码成功率。因此,本发明所提供的图像编码解码方法,具有编码压缩率高和解码成功率高的特点。 【EN】The invention discloses two image coding and decoding methods. In one of the image encoding and decoding methods, after an image is layered on a bit plane by performing binarization processing on the image, a probability distribution model of each pixel constructed by a Context model is adopted to perform sampling encoding on a source so as to improve the compression rate of image encoding. In another image coding and decoding method, a forbidden symbol area is added in a probability distribution model established based on a Context model, so that when an image is decoded, part of code words can fall into the forbidden symbol area, whether the code words fall into the forbidden symbol area is judged in the process of decoding the code words, if the code words fall into the forbidden symbol area, a current decoding path is unavailable, otherwise, the current decoding path is reserved, and then a final decoding result is obtained by adopting a maximum posterior probability algorithm, so that the decoding success rate is improved. Therefore, the image coding and decoding method provided by the invention has the characteristics of high coding compression rate and high decoding success rate.
