Music score recognition method, device and equipment and storage medium

Abstract

The invention relates to the technical field of artificial intelligence, and discloses a music score recognition method, device and equipment and a storage medium, which are used for improving the recognition effect of a handwritten music score. The method comprises the following steps: acquiring a to-be-recognized handwritten music score image; adjusting the handwritten music score image to be recognized according to a preset size, and extracting an image set to be recognized based on the adjusted handwritten music score image; inputting the to-be-recognized image set into a preset feature extraction model for feature extraction to obtain a music score feature matrix of the to-be-recognized image set; inputting the music score feature matrix into a preset feature recognition model for recognition to obtain an initial recognition result matrix; and calling a loss function to optimize the initial recognition result matrix to obtain a handwritten music score recognition result. According to the invention, the handwritten music score recognition effect can be improved, and the recognition result is more accurate. In addition, the invention also relates to a block chain technology, and the related information of the handwritten music score can be stored in a block chain.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a music score recognition method, device, equipment and storage medium. Background technique [0002] Music has always been transmitted mostly through handwritten scores. The digitization and preservation of sheet music is critical to preserving and disseminating a beautiful musical heritage over time. Nowadays, there are tens of thousands of scores waiting to be recorded around the world. Manual recording is time-consuming, laborious and error-prone, which undoubtedly brings great difficulties to music producers and disseminators. Therefore, people are gradually seeking to automatically identify and record scores. technical means. [0003] There are existing sheet music image recognition techniques that can convert sheet music images into a machine-readable format, and some existing tools can also automatically recognize sheet music images. [0004] Ho...
