ease of use
The recognition process is made fully automatic to ensure the highest possible ease of use.
When an image is given to the toolkit it recognizes the location of music on the page, analyses the music and outputs the music in the required format, currently MusicXML. There is no need for the user to specify anything - even where the music is on the page.
This simplicity of function strives for a seamless experience. For a software house considering incorporating the music recognition toolkit this means no addional GUI to contend with.
