Abstract |
In this paper, we proposed an enhanced transform domain intra prediction for H.264/AVC. In the proposed scheme, H.264 intra prediction can be described by generalized linear operation after defining both H-filter and V-filter. Since intra prediction operation can be decomposed into some sparse matrices, we can reduce computational complexity for intra prediction. Our scheme can reduce the number of multiplication and addition operations more than Chen’s by 22.4% and 21.6%, respectively, in each 4×4 block. We can insist that the proposed scheme can be used for fast transform domain intra prediction in the area of transcoding MPEG-2 streams into H.264/AVC streams. |
