[0043] 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.
[0044] The present invention proposes a fractal-based video compression and decompression method. The compression method is a novel video compression coding method that utilizes the fractal iterative principle for video coding. First, block DCT transform coding is used for the initial frame, and non-I frames are encoded. For block motion estimation / compensation coding, first calculate the pixel sum and pixel square sum of sub-blocks related to the sub-block domain and the parent block domain, then use the full search method to find the most similar matching block in the search window of the previous frame, and finally use The Huffman coding method compresses the coefficients of the...
