Artificial intelligence for characterizing plankton traits from images
24-26 of April 2019, Villefranche-sur-Mer, France
The aim of the workshop is to gather researchers interested in applying machine learning to identify and quantify functional traits of aquatic organisms from individual images. A special focus will be given to plankton, but we also welcome participants studying other marine or freshwater organisms.

Thomas Kiørboe is Professor at the Centre for Ocean Life, National Institute for Aquatic Resources, Technical University of Denmark.
His research interests encompass observing zooplankton using high speed video, studying the dynamics of particle-associated microbial communities and marine snow, and understanding how planktonic organisms swim and find their mate and their food.
Jean-François Lalonde is an Associate Professor in Electrical and Computer Engineering at Laval University, Quebec City, since 2013. He is a former Post-Doctoral Associate at Disney Research, Pittsburgh.
His research interests are in computer vision and deep learning, with a particular focus on lighting estimation, 3D reconstruction, tracking, and augmented reality.

The base of marine ecosystems is supported by planktonic organisms that have adapted to extreme environmental conditions. These adaptations, often shared by many species, represent “functional traits” that influence the fitness of individuals as well as ecosystem functioning. A better understanding of these traits appears crucial to predict the responses of marine ecosystems to the unprecedented changes affecting the Ocean. Several traits are associated to morphological features (e.g. size, shape, lipid stores, etc.), hence allowing automatic detection and measurement from images.
Imaging methods for plankton studies have multiplied and rapidly improved over the past decade. They have led to the production of massive amounts of images that are taxonomically classified and stored in easily accessible repositories and therefore particularly amenable to machine learning approaches. Such approaches provide the opportunity to revolutionize the field of plankton ecology and have immediate consequences for scientific research and ecosystem health assessment.
Thus, we wish to foster the development of new tools combining imaging methods and machine learning algorithms to automatically detect and measure important functional traits of planktonic organisms.
Researchers working on estimating the functional traits of other aquatic organisms from imaging and/or artificial intelligence tools are also welcome to participate in order to bridge the transdisciplinary gap .
