This command-line tool (and Python package) allows for the easy extraction of systems of staves from musical scores. In particular, it makes it easy to extract the first system of any musical score that is in B&W format, and has a noiseless enough background
This tool was built to automatically generate incipits for large sets of scores, like those downloaded from IMSLP. It was specifically built to create an index of the 555 keyboard sonatas by Domenico Scarlatti, in a related project.
The package is available on PyPI as incipit and so is available the usual way, i.e.,
sudo pip install incipit
In addition to the Python package, this should also install a CLI binary that is
runnable, called incipit.
Usage: incipit [OPTIONS] INPUT
Extract the first (or any) system of staves from a black-and-white modern
musical score, either available as an image file or PDF. For instance,
$ incipit -o "555-incipit.png" ./input/pdf/555-gilbert.pdf
will extract the first system of staves of the sheet music
`555-gilbert.pdf' as the image `555-incipit.png`. And,
$ incipit --output "1__{}.png" -# '0,-1' ./input/pdf/1-gilbert.pdf
will extract the first and last systems of staves of `1-gilbert.pdf` and
output these as the images `1__0.png' (first system) and `1__10.png' (last
system).
Options:
-a, --audit Visualize system detection across document
-c, --count Output number of detected systems
-p, --pages TEXT List of pages to process (e.g., '0', '0,-1')
-#, --systems TEXT List of systems to extract (e.g., '0', '0,-1')
-h, --height-threshold FLOAT % of height threshold for system detection
-w, --width-threshold FLOAT % of width threshold for system detection
-o, --output TEXT Output file pattern
-v, --verbose Print debug information
--version Show the version and exit.
--help Show this message and exit.
