Hello guys.
I am trying to identify the heroes used in a mobile Android game at runtime. This game has thousands of heroes so I feel like Template matching is not the most efficient way of dealing with this because I would have to find a match for each of them. Scaling might also be an issue depending on the device. I also took a look at Image Recognition but I don't understand how I could do this in my case (offline and using custom images)
Any hint to what to look for would be welcome. Thanks
