基于EMD的音频信号检索

Audio Retrieval Based on the Earth Mover's Distance

介绍了一种基于Mel倒谱参数和EarthMover'sDistance(EMD)度量的音频检索方法,它利用了人耳的感知特性,并结合特征分布之间的距离度量EMD,获得了良好的性能,具有广阔的发展前景。

An audio retrieval theory using Mel-frequency cepstral coefficients （MFCC） and the Earth Mover＇s Distance （EMD） is presented. It applies perceptual feature and a novel measurement of signatures. Results show that good performance is achieved,which gives the wide prospect of this approach.
