| Abstract(in English) | MPEG-4 as video coding techniques is widely used in video distribution. This technique achieves efficient compression by using block-based DOT and motion compensation. Nevertheless, there is a problem that compression quality of cell animation images, which is one of artificial images, is deteriorated to lose high-frequency component in the decoded images at low bit rates. This is caused by the fact that the cell animation images have a feature that intensity values change on the edges more steeply than natural images. To improve the image quality, this paper proposes a method, adaptively processes each region obtained from the cell animation images based on their features the cell animation images. Experimental results are shown to verify the performance of the proposed method. |
