New GNN-based method enhances handwritten music score synthesis for OMR

Researchers have developed a data-driven approach to improve the synthesis of handwritten music scores for Optical Music Recognition (OMR) training. By analyzing inter-glyph distributions from large datasets like MUSCIMA++ and OmniOMR, they found that hard-coded positioning rules in existing frameworks deviate from real handwriting. Their work introduces empirical means that reduce positioning Root Mean Square Error (RMSE) by up to 60% and further refines this with a Graph Neural Network (GNN) that achieves an additional 50-85% RMSE reduction by modeling contextual constraints between glyphs. This improved synthesis accuracy positively impacts downstream OMR tasks, with a YOLOv8 detector trained on the new data showing a significant increase in mean Average Precision (mAP50). AI

IMPACT Improves synthetic data generation for OMR, potentially leading to more accurate transcription of handwritten music.
