Histogram of gradients of Time-Frequency Representations for Audio scene detection

Abstract

This paper addresses the problem of audio scenes classification and contributes to the state of the art by proposing a novel feature. We build this feature by considering histogram of gradients (HOG) of an audio scene time-frequency representation. Contrarily to classical audio features like MFCC, we make the hypothesis that histograms of gradients are able… (More)
