## Deblurring with OpenCV: Wiener filter re-loaded
The problem of deblurring has really caught my fancy though I have only had partial success with it. Deblurring is basically an ill-posed problem where there are 2 unknowns namely the original image and a blurring function. There are many solutions to this problem involving a fair amount of mathematics. Every now and then I will sneak into some white paper on this topic only to beat a hasty retreat gulping for air as I get drowned in the abstract math. Anyway my search led me to the following presentation “ Deblurring in CT (Computer... [More]

## Experiments with deblurring using OpenCV
Deblurring refers to the removal of the blur from blurred images. The removal of blur is extremely important in the fields of medical imaging, astronomy etc. In medical imaging this is also known as denoising and finds extensive applications in ultra sonic and CT images. Similarly in astronomy there is a need to denoise and deblur images that are taken by space telescopes for e.g. the Hubble telescope. Deblurring is really a tough problem to solve though it has been around for ages. While going through some of the white papers on deblurring I... [More]
