Abstract :
In previous work we have used a multi-hypothesis tracking (MHT) algorithm to estimate the number of whales vocalizing at the same time. This paper introduces modifications that exploit the frequency content of clicks, thus allowing promising tracking and classification of both regular clicks and buzzes. Our method is validated with a dataset of Blainville´s beaked whales where the number of animals is known. The results are satisfactory.
