Passive acoustic monitoring of baleen whales in Cap Code Bay: a sparse approach
International audience A sparse representation-based classification algorithm with rejection option dedicated to baleen whale calls is proposed. Sparse representations express a given signal as a linear combination of base elements called atoms belonging to a dictionary. Such representations can cap...
