End of August the German computer magazine c’t published a thorough review of programs that digitize sheet music (18/2019, page 122-126). The three programs that achieved ‘good recognition’ were PhotoScore, SharpEye, and SmartScore with a reported 98% accuracy – the same programs that did well in the review that c’t published in 2001!

There are of course OMR systems in development that do not support MusicXML and may not be able to process a full page. How can the note/rest assessment handle such situations? To address this,…
Assessments of results containing added measures
When OMR systems add additional measures, it is a problem for automated assessments. Can it still be done?
Short update to automated assessments
Evaluating scores on the note level is the first step towards automated assessments. In this blog post, I’ll take a look at how this can be done.
Can automated assessments support OMR evaluations?
At the end of the blog I wrote about OMR competitions a couple of months ago, I mentioned that a prerequisite is automated evaluations. Last two months I familiarized myself with the topic using the excellent paper ‘Towards a Standard Testbed for Optical Music Recognition’ by Donald Byrd and Jakob Grue Simonsen, and the OMRTestSuite…
Can competitions be helpful for OMR Research?
No question: competitions are popular, especially in the data science and machine learning space. The advantages are clear: someone entering the domain can get feedback almost instantly, prices have yielded a high-multiple investment by participants, and new ideas and insights have been gained. A closer look shows different types of competitions: Branded competitions: some of…
