The 2nd Edition of the ImageCLEF Coral Annotation Challenge 2019 Call for Papers

The 2nd Edition of the ImageCLEF Coral Annotation Challenge 2019



The increasing use of structure-from-motion photogrammetry for
modelling large-scale environments from action cameras attached to
drones has driven the next-generation of visualisation techniques that
can be used in augmented and virtual reality headsets. It has also
created a need to have such models labelled, with objects such as
people, buildings, vehicles, terrain, etc. all essential for machine
learning techniques to automatically identify as areas of interest and
to label them appropriately. However, the complexity of the images
makes impossible for human annotators to assess the contents of images
on a large scale.

Advances in automatically annotating images for complexity and benthic
composition have been promising, and we are interested in
automatically identify areas of interest and to label them
appropriately for monitoring coral reefs. Coral reefs are in danger of
being lost within the next 30 years, and with them the ecosystems they
support. This catastrophe will not only see the extinction of many
marine species, but also create a humanitarian crisis on a global
scale for the billions of humans who rely on reef services. By
monitoring the changes and composition of coral reefs we can help
prioritise conservation efforts.


The data for this task originates from a growing, large-scale
collection of images taken from coral reefs around the world as part
of a coral reef monitoring project with the Marine Technology Research
Unit at the University of Essex (currently containing over 2TB of
image data of benthic reef structure).

 Challenge description

Participants will be require to annotate and localise coral reef
images by labelling the images with types of benthic substrate
together. Each image is provided with possible class types.
