Striking similarity to this article, with a lot of the preprocessing steps missing.<p><a href="https://medium.com/@neshpatel/solving-sudoku-part-ii-9a7019d196a2" rel="nofollow">https://medium.com/@neshpatel/solving-sudoku-part-ii-9a7019d...</a>
So,you view the image using CV and write down the coordinates of the puzzle, put them in array and use CV to save the puzzle with different name.<p>Basically, you are cropping the image and saving it - which even a crappy cropping tool does. Do not consider this as a discouraging comment - programming can do better.<p>I understand you are looking for jobs and trying things. If I'm the hiring manager, I would rather prefer a candidate who found puzzle coordinates from the image bits/pixels and suggest cropping regions.
Nice. Would you do a follow-up showing how to automatically select corners like office lens or Dropbox do ? (I find the office lens app really really good)
