Abstract
The conventional DCT would be unlikely to be the best choice for image blocks in which some directional edges other than the vertical/horizontal ones dominate. Directional DCT framework is able to provide a better coding performance for image blocks that contain directional edges. In the light of directional DCT, directional APBT is proposed in this paper. It can also be used in image coding. Experimental results demonstrate that this framework can indeed improve the coding performance remarkably.
