Create a affineTransform proof of concept script that takes one image, finds points within it and to scale and distort an image to and then places it there.

Begin the calibrate script which will read the .txt file made by the normalize script. JSON would make more sense.

Normalize works, I like it. Image size is the real bandwidth limiter but images look good enough. SHould create a script to onionskin all scans for evaluation. Maybe run the holepunch detection on normal and write text file that prints the centers? Will do that now.

Almost blew past a good stopping point.

This script can now, on at least one example. locate the largest contours on the page and then put those contours in an array.
It should also look for the largest, most outlying, to prevent errors in the case of large contours in the image.
They should never go past the holes.
Next step: use this for straightening, which will be good for the image extraction script.
Use them as registration points and then just rotate, shift and "shoot" by cropping at a point relative to the holes.
For calibration/templating, look into pattern matching fiducials after getting hole punch coordinates.

Started analysis script with single example taken from stackoverflow as a starting point. Had to modify it to support opencv 4.x but got it to run. Finds holes.
