Translate a tic tac toe board to text

Let’s say you have a picture of a tic tac toe board after a game is done. I’m trying to make something that would be able to to translate the board to text.

I found this article which seemed to be pretty close but not exactly, also it’s not using Tensorflow.

My assumption is there would have to be some way to split the image into each of the nine different spaces, then check each space for either X,O, or BLANK. That’s the part I’m trying to wrap my head around. I’ve heard of stuff like image segmentation but not sure if that’s what I need.

Thanks!
