Is there a program to automatically find manual marks on sales documents during streaming scanning?

Question

Programming

Good day, forum users.
There is a task - to determine manual deletions on TORG-12, which customers make when accepting products, during streaming scanning.
Prerequisites:
When selling products in your own system, a package of shipping documents is generated. At the same time, data on issued documents remains in the system in digital form.
When accepting, clients may not accept all the goods and therefore make marks in various ways (a crossed out number in the quantity column, a strip along the entire length of the document, a cross in the quantity column, etc.) that the goods are not all accepted. Getting them to make marks is equally impossible.
After returning the documents, the employee scans the TORG-12 barcode and closes the document (if the client has fully accepted the goods and there are no "deletions" in the document) or corrects the client documents in the system.
Because the branch network is distributed over many locations, it became necessary to optimize this activity and leave only streaming scanning of documents received from clients on the ground, and transfer all other functions to a certain SSC (common service center).
This requires a software package that would most likely determine whether or not there are customer marks in the tabular part of TORG-12. All documents without marks must be automatically "closed", and all documents with marks must be sent to the employee for processing (it is desirable to highlight the lines with marks in documents).
Unfortunately, Abbyy and Kofax's solution pilots showed that they recognize documents too well, and 10-12% of "cross-outs" are defined as blank documents.
One of the developers of the comparison of the finished product with the sample (in fact, the comparison of two raster images) did not take up the task, because. I have never encountered a streaming comparison of documents (images).
Maybe you have a suggestion what software solutions can help solve the problem?
