Plug and Play ADMM for Image Restoration

An ADMM image restoration algorithm using denoisers

Plug and Play ADMM is a variant of the standard alternating direction method of multiplier (ADMM) which replaces the explicit image prior using an image denoiser.
Plug and Play ADMM version 1.0 supports the following problem types:
- Image Deblurring
- Image Inpainting
- Image Super-resolution
- Image Restoration of arbitrary linear forward model

and the following image denoisers (Please download at the respective websites):
- BM3D (http://www.cs.tut.fi/~foi/GCF-BM3D/)
- Total Variation (https://www.mathworks.com/matlabcentral/fileexchange/43600)
- Non-local Means (http://www.ipol.im/pub/art/2011/bcm_nlm/)
- Recursive Filter (provided in the package)
