Skew Detection in Music Score Images
Javad Mahmoodi, Jafari, Mehdi · ASME Press eBooks · 2011
This paper proposes a new algorithm for skew detection in music score images. A common method for finding location of staff lines is horizontal projection that is very sensitive to skew. The proposed method consists of four stages, preprocessing, staff line detection, region of interest (ROI) selection and skew detection. After preprocessing, some parameters are extracted for staff line detection and ROI selection. By using ROI, execution time of skew detection is reduced. The proposed method has been applied to several music sheets and skew is detected with a high precision.
