Fixed-rate block based image compression

摘要: An image processing system including an encoder and decoding is provided. The includes decomposer, a block encoder, encoded composer. decomposer decomposes the into blocks. which selection module, codeword generation module construction processes Specifically, computes set of parameters from data values elements in block. generates codewords, uses to derive quantized values. then maps each element's original index one derived reverses this process reorder decompressed blocks output file.
