A common problem with that approach is that errors and artifacts that were made in one stage are propagated through the system and can heavily affect the performance. For example, if the staff line detection stage fails to correctly identify the existence of the music staffs, subsequent steps will probably ignore that region of the image, leading to missing information in the output.

Optical music recognition is frequently underestimated due to the seemingly easy nature of the problem: If provided with a perfect scan of typeset music, the visual recognition can be solved with a sequence of fairly simple algorithms, such as projections and template matching. However, the process gets significantly harder for poor scans or handwritten music, which many systems fail to recognize altogether.

Donald Byrd also collected a number of interesting examples [12] as well as extreme examples [13] of music notation that demonstrate the sheer complexity of music notation. Typical applications for OMR systems include the creation of an audible version of the music score referred to as replayability.

A common way to create such a version is by generating a MIDI file, which can be synthesised into an audio file. MIDI files, though, are not capable of storing engraving information how the notes were laid out or enharmonic spelling. If the music scores are recognized with the goal of human readability referred to as reprintability , the structured encoding has to be recovered, which includes precise information on the layout and engraving.

Apart from those two applications, it might also be interesting to just extract metadata from the image or enable searching. In contrast to the first two applications, a lower level of comprehension of the music score might be sufficient to perform these tasks. The framework has four distinct stages with a heavy emphasis on the visual detection of objects.

They noticed that the reconstruction of the musical semantics was often omitted from published articles because the used operations were specific to the output format. In , Ana Rebelo et al. This framework became the de-facto standard for OMR and is still being used today although sometimes with slightly different terminology. For each block, they give an overview of techniques that are used to tackle that problem. This publication is the most cited paper on OMR research as of With the advent of deep learning , many computer vision problems have shifted from imperative programming with hand-crafted heuristics and feature engineering towards machine learning.

In optical music recognition, the staff processing stage, [15] the music object detection stage, [16] [17] [18] [19] as well as the music notation reconstruction stage [20] have seen successful attempts to solve them with deep learning. Even completely new approaches have been proposed, including solving OMR in an end-to-end fashion with sequence-to-sequence models, that take an image of music scores and directly produce the recognized music in a simplified format. For systems that were developed before , staff detection and removal posed a significant obstacle. A scientific competition was organized to improve the state of the art and advance the field.

However, the freely available CVC-MUSCIMA dataset that was developed for this challenge is still highly relevant for OMR research as it contains high-quality images of handwritten music scores, transcribed by 50 different musicians. Several sub-projects have already been successfully completed, including the Liber Usualis [27] and Cantus Ultimus. The development of OMR systems benefits from test datasets of sufficient size and diversity to ensure the system being developed works under various conditions.

However, due to legal reasons and potential copyright violations, it is challenging to compile and publish such a dataset. Many OMR projects have been realized in academia, but only a few of them reached a mature state and were successfully deployed to users.

Most of the commercial desktop applications that were developed in the last 20 years have been shut down again due to the lack of commercial success, leaving only a few vendors that are still developing, maintaining, and selling OMR products. Apart from the desktop applications, a range of mobile applications have emerged as well, but received mixed reviews on the Google Play store and were probably discontinued or at least did not receive any update since From Wikipedia, the free encyclopedia.
