Local enhancing of license plate in video sequence

edit

My goal is to create an enhanced image with a more readable license plate number from a given sequence of images with indistinguishable license plates on driving cars, such as the sequence below.

As you can see, the plate number is, for the most part, indistinguishable. I am looking into implementations for enhancing such as super-resolution of multiple frames (as I have researched in this paper: http://users.soe.ucsc.edu/~milanfar/publications/journal/SRfinal.pdf).

I have some experience with OpenCV, and I am looking for help in what direction to take, or if super-resolution is really the best option for this kind of problem.
