Hi,

I am working on a project for the Science Exhibition that is going to be held in my college. For the project, I need to detect hand-drawn shapes. And for that, I need some good algorithms.

What data that I have is, an array of points; an array with like tens of hundreds of points; each point being at a specific distance, let’s say, 10 pixels on the hand-drawn shape. Like this :

Any help will be appreciated.

Thanks for the reply. Unfortunately, that doesn’t quite solve the problem.

What I want is an efficient algorithm independent of any programming language like the Mean Shift method but that’s too advanced. I just need basic shapes recognition.
