Thanks! I'm new to the opencv package so many of these functions were unknown to me. I'm going to take a deeper dig on this tonight and contribute my python implementation of what you shared... I'm wondering if 2.4.9 is sufficient or would I need to upgrade to the development 3.0.0 to have all the python bindings of the methods you chose to use?

I will have access to each newly generated template so that wouldn't be an issue. I've also though about writing a classifier to identify handwritten digits only but it would still give false positives on the typed digits within the answer.

I've played around with template matching to try to standardize the submitted assignment versus the template assignment but its not quite getting the job done well and reliably. I've also experimented with keypoint detection but I believe that approach is way overkill for my use case.

Here is an example image of the TEMPLATE:

And a sample image I'm trying to match against:

What would be the best approach in terms of normalizing the sample image (scaling, deskewing), subtracting out the template image, and be left with the remaining text?
