Revision history [back]

I almost reach my goal which is extract data from sudoku puzzle.

• I found the 4 vertices of the puzzle in a picture
• Isolate the puzzle in a new Mat

right new, I have these kind of images which represent a cell of the puzzle:

For the next step, I would like to "focus on the middle" because I think that the ocr engine focus on the border. Is there a way to focus on the middle or will I have to find contour and focus on the contour close to the middle ? What is the next step for you ?

Thank you !

Thank you !
