## 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]

## Deblurring revisited with Wiener filter using OpenCV
In this post I continue to experiment with the de-blurring of images using the Wiener filter. The Wiener filter attempts to de-blur by assuming that the source signal is convolved with a blur kernel in the presence of noise. I am including the de-blurring with 3 different blur kernel radii and different values for the Wiener constant K. While the de-blurring is still a long way off there is some success. One of the reasons I have assumed a non-blind blur kernel and try to de-convolve with that. The Wiener filter tries to minimize the Mean... [More]
