I've tried some OMR (optical music recognition) programs, and although
their performance is still poor compared to OCR, I've been quite
impressed of what they can do.
Imagine we have an OMR package. It can recognize without help from the
user say 25 % of all musical symbols on an image of a music sheet. On
the other hand, given any non-musical image it does not misinterpret
more than half of that amount as music. If such programs do exist, I'd
say that we have an AI algorithm strong enough for a visual music search
engine.
We could try and see. There are free versions and trial versions of OMR
software available out there.
