Introduction
Degradation Model
The block diagram for our general degradation model is
I. Inverse Filter
In this method we look at an image assuming a known blurring function. We will see that restoration is good when noise is not present and not so good when it is.
II. Weiner Filtering
In this section we implement image restoration using wiener filtering, which provides us with the optimal trade-off between de-noising and inverse filtering. We will see that the result is in general better than with straight inverse filtering.
III. Wavelet Restoration
We implement three wavelet bassed algorithms to restore the image.
IV. Blind Deconvolution
In this method, we assume nothing about the image. We do not have any information about the blurring function or on the additive noise. We will see that restoring an image when we know nothing about it is very hard.
V. Conclusions
Nothing but the conclusions.
