I did a multiple-choice grader with image recognition that operated at a fraction of the exorbitant Scantron costs and at the time I thought we had a business model in the bag. Turned out that none of the schools we contacted wanted to actually implement our system because 1: they didn't want to switch from all-paper to paper-digital now to all-digital in the future because education moves at geologic timescales, and 2: nobody had tried it before, so if something went wrong, whoever vouched for the program would get the blame. Just something to consider if you plan to commercialize this application. CYA matters a lot on purchasing decisions.
