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.

Great for removing noise in depth estimation algorithms.

Awesome codes! Would it be possible to extend the current program working on image with complex values as well?

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



Lester Liu


good for image deblurring

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.
