Answer 1

First localize the license plate. To do this, you can use a change in the brightness / contrast of the car number or, as a more reliable option, search for a rectangle according to the specified parameters (aspect ratio / size). You can use opencv to find the rectangle (there is a port for python). Opencv has an example for finding rectangles - squares.cpp. Theoretically, you can implement it yourself in python, then you will need to write Canny operations, blurs, etc.

Answer 2

OpenCV

Answer 3

The BNP (Blur Number Plate) app allows you to automatically blur a car's license plate to hide the number before posting a photo.
