Variational Image Restoration and Decomposition in Shearlet Smoothness Spaces
Min Li, Chen Xu · Chinese Journal of Electronics · 2017
We present the shearlet-based variational model for image restoration and decomposition. The new model can be seen as generalizations of Daubechies-Teschke's model. By using regularization term in shearlets smoothness spaces, and writing the problem in a shearlet framework, we obtain elegant shearlet shrinkage schemes. Furthermore, the model allows us to incorporate general bounded linear blur operators into the problem. The experiments on denoising, deblurring and decomposition of images show that our algorithm is very efficient.
