Recognition of a hand-sketched Tic Tac Toe game

Hello everyone,

I am working on my home project of Tic Tac Toe solver. Its goal is to recognise the hand-sketched Tic Tac Toe game and then dipslay the optimal step.

Currenty, I'm having problems with video recognision as I am quite new to this field. From what I've learnt, I am thinking to try doing some kind of # pattern recognition with Hough transform and then substracting the elemens of each cell of the game.

So my questions is, how would you recommend doing the game recognition? Any ideas welcome and thanks in advance!

You might find this demo very useful. The code is also linked from the page:

Well the problem is that sudoku has a clear border line where Tic Tac Toe does not and I have no ideas how to deal with it
