Research Interest

My main focus are signal processing and pattern recognition applied to Bioacoustic applications. I'm working on detection and localization of marine mammals using passive acoustics. My research project consists to analyse the sound emitted by cetaceans, especially sperm whales, blue whales and recently humpback whales. These studies are based on the segmentation of recordings and on the extraction of the pertinent information for characterizing the species or the individuals.

Current Projects & Collaborations

- Antarctic Blue whales and Pigmy blue whales detection using passive acoustics.
F. Samaran, Univ. La Rochelle

Analysis of acoustic recordings from Indian Ocean and Southern Ocean reveals low frequency with high intensity calls produced by two blue whale subspecies.

- Acoustics observatory for cetaceans detection
H. Glotin, LSIS, Université de Toulon

Cetaceans are present in the Mediterranean Sea. The visual observations could be completed by acoustics observations. This project is to develop an autonomous system for real-time detection of sounds emitted by cetaceans in the Occidental Mediterranean Sea.

- Segmentation and classification of the sound units in the Humpback whales songs

We will rely on the most powerful and the most recent methods and algorithms used in speech processing. The objective is two-fold; it is first a question of indexing the various sound units of the whales present in the area of Madagascar. It is also a question of seeing whether it is possible to use the characteristics of these sounds to identify a speaker (an individual or a group).
