This paper proposes an efficient two-description image coding technique. The two side descriptions of an image are generated by quincunx subsampling. The decoding from any
side description is done by...

In inter-picture coding, block-based frequency transform is usually carried out on the predicted errors for each interblock to remove the spatial correlation among them.
However, it can not always do...
Adaptive Block-Size Transform Based on Extended Integer 8x8/4x4 Transforms for H.264/AVC
Block-Size Transform Extended Integer 8x8/4x4 Transforms H.264/AVC
2010/12/16
In this paper, a low-complexity Adaptive Block-size Transform (ABT) scheme is proposed for the H.264/AVC.The integer 8x8/4x4 discrete cosine transforms with an extended relation are applied to the pro...
