Hi,
I am not sure if I understood your problem (e.g. if you are looking for
"dewarp" ("straighten text line") feature. In leptonica there are example
programs for dewarping: dewarp_reg.c and dewarptest.c. I try it to on one of
my project, but it did not worked on my images (e.g. I plan to play with it
later ;-) )
On http://diybookscanner.org I found references for (commercial) program
Book Restorer [1]. I had change to test it and I can proof it worked perfect
- if you need to straight text lines in output.
I have experience only with these. But if you google for "dewarp" or "Image
straightening algorithm" you can find a lot of interesting suggestions
for algorithm or programs ([2], [3])
