摘要: A novel approach which combines directional spatial interpolation at the receiver and block-based coding is proposed for low bit rate coding. The can reconstruct faithfully a large percentage of blocks that are intentionally not sent. Experimental results show new system provide significant subjective objective gains over conventional approaches still image compression, has potential to be extended video
