Computer Vision for Underwater Environmental Monitoring



Computer Vision for Underwater Environmental Monitoring

By Dr. Alexandra Branzan Albu, University of Victoria, BC, Canada

Abstract: This talk addresses how computer vision techniques can be used for interdisciplinary applications in environmental underwater monitoring. Ocean Networks Canada (ONC), an initiative of the University of Victoria, is a worldwide leader in underwater environmental monitoring. Over the past 10 years, ONC has collected over 83,000 hours of video data from 26 historical and current seafloor camera systems. The speakers will present an overview of the main challenges for computer vision and video processing techniques in underwater imaging applications. These challenges include, but are not limited to:

  • light propagation in underwater media (forward and backward scattering, wavelength-dependent attenuation with distance)
  • presence of floating particles (marine snow)
  • analysis of massive amounts of data (HD videos recorded on a 24/7 basis)The talk will also present several success stories of computer vision algorithms designed for specific tasks of underwater environmental monitoring using visual data acquired by cabled seafloor observatories of Ocean Networks Canada. It will also outline several directions of future work in environmental monitoring that will hopefully inspire and motivate the audience to contribute to this emerging area of interdisciplinary research.

Biography: Dr. Alexandra Branzan Albu is an associate professor with the Department of Electrical and Computer Engineering at the University of Victoria (BC), Canada. She holds a PhD in Electrical Engineering from Politehnica University of Bucharest. Alexandra’s research focus is on computer vision. From a practical standpoint, her contributions to this field involve raising and solving research questions that are closely linked to societal needs such as environmental monitoring, medical imaging, rehabilitation, and aging-in- place. Due to the interdisciplinary and applied nature of the research problems under investigation, Alexandra has developed a number of industrial collaborations with companies such as Intel, SAP, Kongsberg-Mesotech, who have all provided funding for her research. Her research is also funded by NSERC. She is a member of the Ocean Observatory Council, which provides formal and informal advice from a user perspective on the Ocean Networks Canada (ONC) science plan and on details of ongoing operations to maintain, fix, and expand the observatory. She is currently on study leave, and a visiting scientist at Ocean Networks Canada.
