Realtime image classification!

Me in 2019:
22075ms to find all occurrences of a string of the screen

Don't compare with other people, they failed more than you may have tried so keep on coding 🙈

If you scanned screen pixel by pixel, then find all groups of contiguous black pixel, each of these groups sent into a classificator to decode the char, assembled char in words based on distance between groups to detect whitespaces, assembled words and whitespaces into a string and then made the string research maybe I can believe it 😅
