deconvtv - fast algorithm for total variation deconvolution



Fast numerical solver for total variation regularized least-squares deconvolution problems.

File Information

Total variation regularized least-squares deconvolution is one of the most standard image processing problems. This package provides an implementation of the current state-of-art algorithm using the concept of augmented Lagrangian [1], which can be considered as a variation of the popularly known Alternating Direction Methods of Multipliers (ADMM). The user interface of deconvtv is identical to the current MATLAB's deconvolution tools, including deconvwnr, deconvlucy, and deconvreg:

out = deconvtv(img, psf, mu, opt);

deconvtv supports direct space-time processing for both image and video deconvolution problems.

Applications of deconvtv include, and are not limited to: image and video deblurring, image and video denoising, depth data enhancement, hot-air turbulence stabilization, and multi-view synthesis.

Very neat codes.
And for mac system, I just cancel the lines about memory to make it work.

The code is fairly easy to use. I try it for image denoising. The speed is really fast even though it's a global operation.

Error using memory
Function MEMORY is not available on this platform.
Error in deconvtv (line 69)
