Fractal Image Compression Encoding Using M Collection
Ying Jiang · Journal of Shenyang Jianzhu University · 2007
A fixed compression dictionary is created to change the fact that an image has one-to-one compression dictionary and advance the application of the Mandelbrot image in fractal image compression algorithm.The function with different z can create different curves.The paper uses the rule to quantify the curves and then obtain many image blocks,thus abundant compression dictionary is built.During the encoding,the domain blocks are divided up in manner of self-adopt combination and match the image blocks in the compression dictionary,and then the image block which meets the demand will be encoded.During the decoding,reading from the compression dictionary,the former image should be restructured.Using this algorithm,a better result can be obtained because of the abundant compression dictionary.The experiment proves that the algorithm,which has fine compression effect and perfect decoded image,is timesaving,simple and feasible.
