从稀疏表示到低秩表示(三)

从稀疏表示到低秩表示(三)

确定研究方向后一直在狂补理论,最近看了一些文章,有了些想法,顺便也总结了representation系列的文章,由于我刚接触,可能会有些不足,愿大家共同指正。

从稀疏表示到低秩表示系列文章包括如下内容:

 

一、 sparse representation

二、NCSR(NonlocallyCentralized Sparse Representation)

三、GHP(GradientHistogram Preservation)

四、Group sparsity 

五、Rankdecomposition

 

 

 

 

三、GHP(GradientHistogram Preservation)

此部分是上篇的续篇,介绍sparse representation 的改进

 

GHP(CVPR’13, TIP’14)

• Like noise, textures are fine scale structures in images,and most of the denoising algorithms will remove the textures while removingnoise.

• Is it possibleto preserve the texture structures, to some extent, in denoising?

• We made a goodattempt in:

[1] W. Zuo, L. Zhang, C. Song, and D. Zhang, “Texture Enhanced Image Denoisingvia

Gradient Histogram Preservation,” in CVPR 2013.

[2] W. Zuo, L. Zhang, C. Song, D. Zhang, and H.Gao, “GradientHistogram Estimation

and Preservation for Texture Enhanced Image Denoising,” in TIP 2014.
