Compressed Domain Content-Based Retrieval of MP3 Audio Example using Quantization Tree Indexing and Melody-Line Tracking Method

摘要

In this paper, the content-based retrieval of audioexample based on MP3 digital music archive is considered. In our proposed method, the Sub-Band Coefficients (SBC) in a MP3 frame is used for feature extraction. Both Quantization-Tree indexing (QT) approach and the Melody-Line Tracking (MLT) approach are proposed for indexing MP3 objects. Finally, a two-stage comparison method is used to measure the similarity between MP3 objects. We also employ the measurement of the similarity between query sample and database items. Evaluations on a content-based MP3 retrieval system are performed. Experimental results show that our proposed approach can achieve good performance and high accuracy.
