Anyone here handy with music (score) OCR? (Re: In a languid mood/Louis Gallo)

[RJVB]

Hi,

I obtained a scan from Louis Gallo's In a languid mood (a tribute to Eddie Lang) which I've been trying to convert to a MuseScore file. Without much success. Normally I get better results when I use my own Audiveris install rather than the copy they have running on the MScore site but not in this case.

Is anyone here handy with this? Not asking for a hand-corrected document of course...

Thanks,
R.

For what it's with, my opinion is that your document is much too jargon rich to translate - has an awful lot of musical notation and symbols. I think you'll have to remove most of that if you want to get anywhere with converting it.

In my experience (last time I tried it was probably half a year ago) is still not mature enough to be faster than typing it into MS by hand. But a lot of it depends also on the resolution of the scan. In the handbook they mention a software that was originally developed to "upsample" (what again is the correct word for graphics?) manga comics. It's on GitHub. You could try to create a higher resolution with it. But you need at least 16 Gigs of RAM. It crashed my 8 Gig machine once when I tried it. Or a suitable graphic card.

Good luck. I think the resolution is too low. You are quicker by typing.

The word I was looking for is "upscaling". This is the handbook page about improving the input files.

Hmmm, thanks for the pointer. The file that I uploaded is actually a 1200 DPI file, which is too much for Audiveris, but I got it from a larger PDF bundle containing scans that I don't know the resolution of. I haven't yet tried the 300DPI version I created since (which also has had some filtering comparable to what's described though I didn't yet attempt any spatial ones to smooth out the jaggies. Then again that's what the waifu upscaler probably does too, in a much fancier way.

I'll give it another shot between chores but Mick may be right that there's too much jitter from the fingering and other indications (Audiveris does have a setting for those). The reason it looks so "charged" is exactly why I want to get it into MuseScore and print out a more easily readable copy!
However, entering a score like this by hand is not really an option if you don't have an appropriate midi input interface (that you know how to play!) but have to make do with a computer keyboard. Even adding fingerings is an ordeal.

Entering a score by hand into MuseScore is rather simple once you learned the key commands which are quite intuitive IMO. It's letter keys for pitches, number keys for durations, arrow keys and modifier keys for certain actions. And it is well documented (albeit not as well and structured as Lilypond) and has a very helpful forum.

Easy doesn't mean fast or not awkward...
