*** CALL FOR PARTICIPATION ***

*The 3rd Edition of the ImageCLEF Coral Annotation Challenge 2021*
Data
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.

*New for 2021:*

in its 3rd edition, the training and test data will form the complete set of
images required to form a 3D reconstruction of the environment. This allows
the participants to explore novel probabilistic computer vision techniques
based around image overlap and transposition of data points. Participants
will be given instruction on the preparation of 3D reconstruction, the
output files (.obj) and a visualisation of each model without labels (for
example, https://skfb.ly/6SooQ).

In addition, participants are encourage to use the publicly available NOAA
NCEI data
<https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=gov.noaa.nodc:0211063>
to
train their approaches.

*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.

*Data*

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.
Substrates of the same type can have very different morphologies, color
variation and patterns. Some of the images contain a white line (scientific
measurement tape) that may occlude part of the entity. The quality of the
images is variable, some are blurry, and some have poor color balance. This
is representative of the Marine Technology Research Unit dataset and all
images are useful for data analysis. The images contain annotations of the
following 13 types of substrates: Hard Coral – Branching, Hard Coral –
Submassive, Hard Coral – Boulder, Hard Coral – Encrusting, Hard Coral –
Table, Hard Coral – Foliose, Hard Coral – Mushroom, Soft Coral, Soft Coral
– Gorgonian, Sponge, Sponge – Barrel, Fire Coral – Millepora and Algae -
Macro or Leaves.
The test data contains images from four different locations:

   - same location as training set
   - similar location to training set
   - geographically similar to training set
   - geographically distinct from training set
