[0143] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings. Only the brightness component Y is taken as an example, and the compression steps of the color difference components U and V are the same as the brightness components.
[0144] An object-based fast multi-object stereoscopic video fractal compression and decompression method selects the middle object as a reference object and uses MCP compression, and other objects use DCP+MCP compression. The intermediate object is a reference object, using a separate motion compensation prediction method MCP coding, using the video segmentation method to obtain the video object segmentation plane, that is, the Alpha plane, using block DCT transform coding for the initial frame, and performing block motion estimation / compensation coding for non-I frames, Calculate the pixel sum and pixel square sum of the sub-block related to the sub-block domain and the parent blo...
