Hi Liang, Thank you for you letter. If I got you right you are working with well formed pdf images. My skills and interest lie more in the field of recognizing scanned pages (skewed, distorted, with sudden brightness/contrast splashes). I think I could build a module that would recognize such scans and turn the music information into some intelligible form (I'm not well acquainted with MS score internal representation yet). Yes it would be nice to work on recognizing clefs and notes and the like. BTW one thing that I saw in one of the systems - counting score timing as a sort of control sum to check that everything has been recognized well. For text recognition it woulld be great to use libtesseract as it has all the things in place. BTW do you know anything about the Audiveris project? On thier site they claim MS integration as their goal.
