可以认为是慢衰落的一种，指的是在一定时间间隔内(块)衰落系数保持不变，而在块块之间又满足频率选择性衰落
The edge smoothing block filtering further computes a cost difference between pixels within a candidate pixel neighborhood and pixels within a current pixel neighborhood, and filters the current pixel based on the cost difference. Aspects of the filters and filter element combinations may preserve edges...

Aspects of an edge smoothing block filter and combinations of the filter with a motion compensated temporal filter are described. In one embodiment, edge smoothing block filtering includes selecting a current pixel to be filtered and selecting a candidate pixel within a search area about the current...
The incremental block-state structure is also extended for the multirate recursive filtering case. The techniques of scattered look-ahead, clustered look-ahead, decomposition, and incremental output computation are combined to introduce several pipeline stages inside the recursive loop of the block ...

BM3D(Block-Matching and 3D filtering)读后感 一、 总览 BM3D是2007年TIP的文章,题目是Image denoising by sparse 3D transform-domain collaborative ltering,论文、项目的地址是http://www.cs.tut.fi/~foi/GCF-BM3D/,提供matlab代码;http://www.ipol.im/pub/art/2012/l-bm3d/为C++的实现,这篇论文里面有对...
The fact is... I wantedMyPornBlocker™to be much more than just a porn filtering software application. I wanted it to be the one piece of software every family could rely on to block all uninvited content that may be harmful to children. ...
Filtering mode for intra prediction inferred from statistics of surrounding blocks The present invention relates to intra prediction which may be performed during encoding and/or decoding of an image signal. In particular, the present invention relates to intra prediction of a current block, during ...
