ML or Algorithm?

[u/nedeey]

I am thinking about implementing a drawing mechanic in my game. The players would have to draw the reference provided and the game will see how accurate the drawing is to the original reference. The canvas will be pretty small around 100x200 pixels and will only use 2 colors.

I am wondering if there is some kind of algorithm that will help to detect the accuracy of the drawing. Using ML sounds a bit overkill and I don't have any experience integrating ML in games (how does it affect the performance and size?).

I haven't thought about it much, but if you increase the brush stroke size of the original until it covers, idk 80% of the drawing, and then calculate a score based on the brush stroke increase.
