I’m trying to develop an app that can detect the edges of shapes and then fill that shape with colour or certain patterns.
Something like a document scanner in that it will scan the shape and then instead of zoom and crop the documents I want to fill them with colour. Having a hard time going about it, anyone with any ideas?
I’ve tried to use edge detection and the a hough transform to find the shapes but I can’t really get anything to work.
Any advice is greatly accepted!
