the proposed algorithm used adaptive operators for every sub-band to suppress these energy-concentrated coefficients on the block boundary to reduce blocking artifacts in space domain 通过为各个子带设置自适应操作算子去抑制块边界系数能量聚集现象,使得空域中的块效应得到消除。
the block-based discrete cosine transform ( bdct ) suffers from visible blocking artifacts between adjacent image blocks at low bit rates, which reduces the image visual quality 摘要块离散余弦变换在低比特率时其恢复图像的块边界上会出现明显可见的方块效应,从而降低了图像的视觉质量。
this paper proposed a blocking artifacts reduction algorithm based on feature analysis in wavelet domain in order to reduce blocking artifacts while preserving edge and texture information 提出一种基于小波域特征分析的去块效应算法,目的是尽量消除块效应的同时充分保护图像的边缘信息。
