Sperm whales (Physeter macrocephalus) produce short duration acoustical clicks while diving to search for food, each click composed of several pulses. The time interval between consecutive pulses, the interpulse interval (IPI), can be used to estimate the length of the whale. IPIs have been estimated from whales of unknown orientation by processing several hundred clicks and averaging the results. In this work, discrete wavelet transforms and autocorrelation-based methods are used to obtain IPI… CONTINUE READING
