Note Onset Detection Based on Matching Pursuit
摘要
Abstract
Note onset detection is the preliminary work for recognition of high-level musical feature ,such as pitch ,rhythm , tempo and paragraphs ,in content-based music information retrieval .This paper proposed two novel algorithms based on matching pursuit (MP ):the algorithm of MP degree of explaination and the algorithm of MP change of partial .Firstly ,the musical signals were decomposed through MP ,and then the code books were analyzed with the two algorithms .Finally ,a modified peak-picking algo-rithm was applied to generate note onset vectors .The experiments showed the performance of our algorithms was nearly as good as that of 2011 MIREX .关键词
