*** CALL FOR PARTICIPATION ***

*The 4th Edition of the ImageCLEF Coral Annotation Challenge 2022*
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 2022:*

Previous editions of ImageCLEFcoral in 2019 and 2020 have shown
improvements in task performance and promising results on cross-learning
between images from geographical regions. The 3rd edition in 2021 increased
the complexity of the task and size of data available to participants
through supplemental data, resulting in lower performance than previous
years. The 4th edition plans to address these issues by targeting
algorithms for geographical regions and raising the benchmark performance.
As with the 3rd edition, the training and test data will form the complete
set of images required to form 3D reconstructions of the marine
environment. This will allow the participants to explore novel
probabilistic computer vision techniques based around image overlap and
transposition of data points.

*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. ImageCLEFcoral 2022 consists of two
substaks:

   - Coral reef image annotation and localisation:

   - Coral reef image pixel-wise parsing:

*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. The images partially overlap with each other and can
be used to create 3D photogrammetric models of the marine environment.

Substrates of the same type can have very different morphologies, coloUr
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 colour balance due
to the cameras being used. This is representative of the Marine Technology
Research Unit dataset and all images are useful for data analysis. The
training set used for 2022 has undergone a significant review in order to
rectify errors in classification and polygon shape. Additionally, the 13
substrate types have been refined to help participants understand the
results of their analyses.
