Music infringement detection method

Abstract

The invention relates to a music infringement detection method. The method comprises the following steps: S1, performing short-time Fourier transform on each piece of music in a music library in sequence to obtain a frequency spectrum signal corresponding to each music ID; S2, performing dynamic resolution compression on the frequency spectrum signals; S3, for the compressed frequency spectrum signals, calculating an extreme point of each frequency band interval; S4, filtering the extreme points, and obtaining music vectors of the music library through pairwise subtraction of the extreme points; S5, compressing the music vectors of the music library into int32 bit by bit; S6, constructing a hash table by taking int32 as a Key and music ID as Value, and progressively increasing the music IDaccording to the time sequence of the music entering the music library to mark each piece of music; S7, inputting a training audio to obtain an infringement probability; and S8, inputting a test audio to obtain an infringement probability. According to the method, the spectrum information of the music is subjected to feature extraction through the convolutional neural network and the full-connection network, useful features can be extracted in multiple dimensions, manual screening is not needed, and the detection accuracy and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a music infringement detection method. Background technique [0002] The current popularization of the Internet has also brought about the widespread popularity of music. People can easily listen to and use music in various ways to create videos. But music is copyrighted. If copyrighted music is used in commercial videos at will, it will cause infringement and damage the rights and interests of music creators. [0003] The patent publication number CN101493918A discloses a music infringement method, specifically: [0004] The present invention relates to an online music piracy monitoring method and system, comprising the following steps in turn: an audio fingerprint extraction module obtains an audio download address from the Internet: an audio fingerprint extraction module reads an audio file from the audio download address, and obtains an audio file after p...
