| Abstract: | A simple and practical rectangular transform and the vector quantization technique are described. A method for image data compression by combining the rectangular transform with vector quantization technique is presented. By using this method, the dimension of vector coding and the size of the corresponding codebook are reduced; the vector encoding process is picked up; and also the coding rate is reduced. The results of simulation' show that this coding method is very effective in the field of image coding. |
