Abstract(in English) | Discrete consine transform (DCT) is widely used as a method of image coding. In the image coding scheme using DCT like JPEG, the DC coefficient is predicted by using the correlation of neighboring blocks. Further, the prediction is done on the AC coefficient in MPEG4, However, the prediction of the AC coefficient is difficult because the correlation of it is low, and the efficiency may reversely lower by the prediction. By using all blocks in the image, it may be able to do the prediction which is better than the conventional method. In this paper, we propose and examine new prediction system of the AC coefficient using all blocks. |
