We are having some standard deblurring methods like Weiner filtering, regularized filtering, blind deconvolution. But some are effective yet complex and some need so many iterations. Sometimes iterations need to be backward.
Can someone suggest how to improve deblurring using these, or if someone has a better technique?
Deblurring is the process of removing blurring artifacts from images [input image say B which is blurred image which generally happens due to camera shake or some other phenomenon].
A good deblurring method is to use variational analysis in images
Is SeDDaRA (Self-Deconvolving Data Restoration Algorithm) maybe what you are looking for?
True, but what can one do if the point spread function is also unknown... It would be guessing, not?
Yes, that is why it is called Blind. Thank you Lambert Ji, for your all time guidance.
Sandeep, I'm not entirely sure if your application is blind or not. If not, that is you have a characterization of the point spread function, then the ForWaRD algorithm works about as well as other algorithms and there are many. ForWaRD has the advantage of being relatively simple to understand and implement. Most of the work is done by a Wiener filter followed by a wavelet denoising step. If you do not know the PSF, there are also many approaches to the blind problem. The CSAIL group at MIT has a good (in depth) overview paper "Understanding Blind Deconvolution Algorithms": http://people.csail.mit.edu/billf/selectedPublications.html.
try Richardson-Lucy or Landweber algorithms, they can provide acceptable results.
