| Abstract: | Mathematical morphology is the overlapping science of synthesizing multi-disciplinary knowledge and a non-linear theory of image analysis, which has become one of important tools for image processing. This paper simply introduces mathematical morphology and its basic operation of binary morphology： erosion and dilation, and then proposes an algorithm of musical score lines detection based on mathematical morphology. The experiment results indicate that the proposed algorithm has the advantages such as fast computation, high efficiency and strong anti-noise ability compared with the algorithm of Hough transform for detecting straight lines. |
