Abstract

Automatic classification of seismic sources finds vast application security domain. Due to restricted computational power in the edge devices a robust and less complex features need to be extracted and sent to appropriate classifier. Such features are histograms of oriented gradients. It represented the relative spectral distribution of derivative of amplitude against frequency instead of average spectral envelope.
