Abstract： |
The invention relates to a method for anti-error encoding and decoding image based on the distributed source encodings, which includes: it decomposes the encoding image X by using Laplace pyramid to achieve a image with a low resolution and a residual image. Then, it encodes the image with a low resolution to achieve code stream B1 and directly discards the residual image. Then, it transforms X and divides the quantified value into sliced planes. Then, it carries out channel coding about each plane to achieve checking bit and multiplex them into checking bit flow B2. The decoding method is a reverse process of the encoding. |
