Musical score recognition: A hierarchical and recursive approach

Musical scores for live music show specific characteristics: large format, orchestral score, bad quality of (photo) copies. Moreover such music is generally handwritten. The author addresses the music recognition problem for such scores, and show a dedicated filtering that has been developed, both for segmentation and correction of copy defects. Recognition process involves geometrical and topographical parameters evaluation. The whole process (filtering + recognition) is recursively applied on images and sub-images, in a knowledge-based way.<
