The matched reassignment applied to echolocation data
(2019) IEEE International Conference on Acoustics, Speech, and Signal Processing 2019 In Proceedings of the ... IEEE International Conference on Acoustics, Speech, and Signal Processing. p.8236-8240- Abstract
- Previous studies have shown that measurements of beluga whale (Delphinapterus leucas) and bottlenose dolphin (Tur-siops truncatus) echolocation signals at off-axis angles may be well modeled using a Gaussian bell function or a chirped Gaussian function as envelope. In this paper, we apply a novel technique, the matched window reassignment, for investigation of a range of models of dolphin echolocation transients. Using a set of parameterized skewed envelopes and a dictionary-based estimation algorithm, it is shown that the Rényi entropy can be used as an evaluation measure of the model fit. Acoustic recordings from an array of hydrophones of a beluga's echolocation signal are investigated, where the Gaussian envelope frequency modulation... (More)
