Hey, sorry for not getting back to you earlier.
Sure, I think you can get a high accuracy at least with the right
constraints (e.g. requiring filling bubbles completely) and maybe some
human interaction to catch corner cases.
About your three points:
1. SDAPS does not contain anything for this. Unfortunately I have no
idea what error rate is realistic here and how much work it is to
implement something reasonable.
2. I think this is fully implemented.
3. A grid test result should be relatively easily implemented (it
either is just a grid of "bubbles"/checkboxes which would already
work or one would need to add some recognition code which should be
relatively simple).
So, it is probably possible, but in particular the first part requires
research and implementation work.
To answer your other questions:
1. SDAPS mostly is licensed under the GPLv3+, you need to follow the
terms of the license (which basically means providing the source
code of SDAPS and your modifications under the same license terms to
anyone receiving a copy).
2. SDAPS is quite modular at this point. You could easily write a
module which extracts all the information that you need to do
further processing.
3. Not sure what you mean here. Guessing you mean examinations by
"tests" the answer is no. This is simply outside of the scope of the
main SDAPS program.
4. Someone created a grid layout answer sheet generator. Can't find the
link right now though (it is on github).
5. As said in answer #1 you will need to keep within the limitations of
the GPLv3+ (or LPPL1.3c+). I would be delighted if you go beyond
this though and actively provide modifications publicly so that they
can be integrated back. This is open source approach has advantages
for all parties. Me as SDAPS is further improved. You as you get
code reviews (quality assurance) and it makes it a lot easier to
maintain any modifications that you may need in the long run.
Regards,
Benjamin
