Special Session: “Wildlife Bioacoustics and Adaptive Signal Processing”, IEEE ICASSP 2019 (Brighton, UK)

– Special session at IEEE ICASSP 2019

Organisers: Dan Stowell, Naomi Harte, Theo Damoulas

 

Summary:

Wildlife bioacoustics is witnessing a surge in both data volumes and computational methods. Monitoring projects worldwide collect many thousands of hours of audio each [1,2,3,4], and computational methods are now able to mine these datasets to detect, isolate and characterise recorded wildlife sounds at scale [2,5]. Such bioacoustic data is crucial for monitoring the rapid declines in many wildlife populations [6], as well as advancing the science of animal behaviour.

However, many open problems remain, including:

  • detecting/discriminating very brief low-SNR sounds;
  • estimating distance to animals from single-microphone recordings;
  • integrating evidence from multiple sensors, and from differing sensing sources (e.g. radar plus acoustics);
  • sampling bias, imbalance and concept drift in data sources;
  • high-resolution and perceptual measures of animal sound similarity;
  • sound source separation and localisation in complex wildlife sound scenes.

These problems must be solved in order to bring the data fully to bear on urgent global issues such as the loss of animal habitats.

New methods come from machine learning and advanced signal processing: matrix factorisations, deep learning, Gaussian processes, novel time-frequency transforms, and more. These new methods have been shown to be useful in various projects, across many species – bird, bat, cetacean and terrestrial mammals. However, much of this happens in isolated projects and there is a need to bring together lessons learned and establish state-of-the-art methods and directions for the future of this field.

The topic of computational wildlife bioacoustics is growing but lacks any dedicated conference or workshop. ICASSP is an ideal event through which to strengthen the application and the development of signal processing work in this increasingly important domain.

 

Submissions:
