Some Image and Video Processing: Motion Estimation with Block-Matching in Videos, Noisy and Motion-blurred Image Restoration with Inverse Filter in Python and OpenCV

The following problems appeared in the exercises in the Coursera course Image Processing (by Northwestern University). The following descriptions of the problems are taken directly from the exercises' descriptions. The next figure shows the problem statement. Although it was originally implemented in MATLAB, in this article a python implementation is going to be described. The following figure shows how the images get more and more blurred after the application of the nxn LPF as n increases.
