I need to extract information on lines that users draw in my application. I.e. If i user paints a line (in a typical painting app) I need to know how sharp/spiky the line is at places, and how round its edges are at others. In theory it would be able to tell the difference between a circle or square or hexagon or any random scribble. A sort of gesture classification for an infinity number of complex shapes and user scribbles.
I am thinking about methods which involve just letting the user draw a straight image and then processing it, using 2d Fourier transforms and all sorts of nasty processor intensive routines, but these approaches do not have the accuracy I need, and the eat up too much computational time. Another option is to try implement some kind of of spline system, but I am unsure of how to do this. Any other ideas?
