Music score identification classification and playing control method

Abstract

The invention discloses a music score image recognition method and a playing control method, and the method comprises the steps: obtaining a to-be-processed music score: removing useless points on themusic score through a K-nearest neighbor algorithm, and carrying out the Gaussian-based processing of the music score. Edge detection of the Laplacian operator is carried out to obtain music score content; Obtaining the position of a music note by using an LSD algorithm, and judging the category of the music score according to the linear position and the relative distance; Carrying out classification through a music score classifier, and carrying out image segmentation on the classified music score to obtain an image of an independent note; The obtained image is divided into a surface layer and an inner layer, the surface layer identifies notes, the inner layer identifies continuous notes, the surface layer and the inner layer are respectively input into a convolutional neural network, the identified results are combined to obtain complete notes, and the notes are associated with corresponding motor control feeding, so that the purpose of autonomously identifying the music score and the musical instrument by the numerical control platform is achieved. Compared with other existing similar methods, the music score recognition method and device have the advantages of being wide in recognition range, high in recognition precision and robustness and the like.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a music score image recognition and classification method. Background technique [0002] Machine vision refers to converting the ingested target into an image signal through machine vision products, sending it to a dedicated image processing system, obtaining the shape information of the captured target, and converting it into a digital signal according to pixel distribution, brightness, color and other information. The system performs various calculations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions according to the results of the discrimination. [0003] Most of the existing music score image recognition methods can only recognize specific music scores (such as separately identifying staves or numbered musical notations), and some image recognition methods are still based on traditional computer recognitio...
