Image Augmentation using fastai

Hi all,
My pregnant car’s wife was hit by a hit and run car. We went to the police but apparently they are not interested to investigate the case. I succeeded to get the footage and went to a graphic designer but he told me the video was too noisy and have a dark contrast. I am still trying to figure out a way to find the license plate (at least 2 numbers ) via the fastai library.
Any help will be appreciated.
This is what I’ve done so far:

The link of the footage, I am looking for the LP of the white car 6:31pm

All the best
