- The optical music recognition (OMR) field studies how to automate the process of reading the musical notation present in a given image. Among its many uses, an interesting scenario is that in which a score captured with a camera is to be automatically reproduced. Recent approaches to OMR have shown that the use of deep neural networks allows important advances in the field. However, these approaches have been evaluated on images with ideal conditions, which do not correspond to the previous scenario. In this work, we evaluate the performance of an end-to-end approach that uses a deep convolutional recurrent neural network (CRNN) over non-ideal image conditions of music scores. Consequently, our contribution also consists of Camera-PrIMuS, a corpus of printed monophonic scores of real music synthetically modified to resemble camera-based realistic scenarios, involving distortions such as irregular lighting, rotations, or blurring. Our results confirm that the CRNN is able to successfully solve the task under these conditions, obtaining an error around 2% at music-symbol level, thereby representing a groundbreaking piece of research towards useful OMR systems.
