It is definitely necessary to correct the translation/rotation/scale. Doing a correction using the checkboxes themselves might be possible in general. It would probably work best if use rounded checkboxes, as then you could search for them using a simple hough transformation that is even rotation insensitive (though scale might be a bit of an issue). Now I have once tried for a bit to implement something like this (well, using circular corner marks). I utterly failed, but I do think it should work fine in general. > 2) Let's say I'm ok with less accurate recognition - can I force SDAPS > to create/recognize surveys without the corner marks?
