Hi,
I assume you are talking about OMR or Music OCR. See
https://en.wikipedia.org/wiki/Music_OCR.
As far as I understand, OMR is quite different from OCR. Of course, there
are similarities, but music is quite different from text.
Of course, everybody wants to take a photo of a sheet music and have a
perfect digital version to modify, play, transpose etc... so there is no
question about the interest of such a feature. There are several endeavors
in MuseScore and the free software community regarding OMR.
First, there is Audiveris http://audiveris.org The V4.3 is the last public
version and work is going on privately for Audiveris 5. I have no idea what
the status is. MuseScore.com provides a PDF to MuseScore service as best
effort thanks to Audiveris 4. https://musescore.com/import
Audiveris is in the work for years. I fear that starting such an effort
from scratch would be very hard.
Several years ago, MuseScore's lead developer Werner Schweer started
another effort which does use some OMR techniques but has a different
approach. He wanted to make it easier to transcribe existing sheet music
manually. So he implemented staff, barline detection and a UI to sync
images with MuseScore sheet music. It looked like this
http://www.screenr.com/g1Bs Unfortunately, this feature didn't make it in
MuseScore 2.0.
During the last 6-8 months, Liang Chen
http://homes.soic.indiana.edu/chen348/ revived this code and upgrade it, so
this feature is present again in the current master (and in the nightly
builds https://musescore.org/en/download#Nightly-versions). It's still a
work in progress and Liang is still working on it. Some things are better
than the previous implementation, others are missing (for example Werner
used Tesseract to extract titles etc..., and this has not been added back).
If you want to help, take a look to the existing code, build MuseScore and
pass by IRC #musescore on freenode.net to discuss the current state and
future development. You can also see the README in the OMR directory
https://github.com/musescore/MuseScore/tree/master/omr#updates-on-optical-music-recognition
I didn't touch about live handwritten music recognition because your email
talked about printed score recognition but that's also close from OCR and
of course, some people want this, in particular on touch based devices and
with the buzz about proprietary software (Staffpad, notateme,...) . As far
as I know, there is no free software effort in this direction (If anyone
knows about such a project, please share!).
