Antarctic Blue Whale Calls Detection Based on an Improved Version of the Stochastic Matched Filter
International audience As a first step to Antarctic Blue Whale monitoring, a new method based on a passive application of the Stochastic Matched Filter (SMF) is developed. To perform Z-call detection in noisy environment, improvements on the classical SMF requirements are proposed. The signal’s refe...
