There are two activities in the ICCV 2021 AI-enabled MIA-COV19D Workshop:

A. AI-enabled Medical Image Analysis (MIA) Workshop

A1. Scope

AI-enabled Medical Image Analysis (MIA) Workshop is devoted to medical image analysis, with emphasis on radiological quantitative image analysis for diagnosis of diseases. Our focus is placed on Artificial Intelligence (AI), Machine and Deep Learning (ML, DL) approaches that target effective and adaptive diagnosis; we also have a particular interest in approaches that enforce trustworthiness and automatically generate explanations, or justifications of the decision making process.

A2. Call for Participation

Technologies and topics to be addressed include, but are not limited to:

  • 2D/3D-CNN, CNN-RNN, GANs and ML models in medical image diagnosis
  • Sensing “salient features” of Deep Neural Networks (DNN) and AI models related to  decision-making, in spatial (images), temporal (video) and volumetric (3-D) data
  • Optimal visualization of salient features and areas in the input data
  • Low/Middle/High-level feature extraction, analysis and interpretation
  • Exploration of how predictions in data streams are correlated and explain each other (multimodal data)
  • Joint optimization of positive and negative saliencies
  • Global and local models for prediction, or classification
  • Attention and self-attention mechanisms in DNNs/AI approaches
  • Explainable AI based on anchors, or attention
  • Interpretability at training time through adversarial regularization
  • Learning new data (from multiple sources) by leveraging knowledge already extracted and codified, through domain adaptation
  • Uncertainty estimation and quantification, self training
  • Zero/one shot learning, avoidance of catastrophic forgetting
  • Evaluation of explanations generated by ML/DL/AI models in medical imaging

Original high-quality contributions will be targeted in a variety of contexts: in enforcing shared patterns to emerge directly from data; in supporting automated segmentation of CT data; in using visual attention both to improve classification accuracy and to provide interpretability of model outputs; in highlighting the areas in the medical imagery responsible for the provided decisions; in supporting medical staff in their analysis.

A3. Important Dates

For the papers to be submitted to the Workshop (not including the Competition) the timeline will be as follows:

  • July 19, 2021: Paper submission deadline; Start of review period
  • August 6, 2021:  End of review period
  • August 10, 2021: Review decisions sent to authors; Notification of acceptance
  • August 17, 2021: Camera ready version deadline

A4. Submission Information

The peer review process for the papers will be double blind, including at least two distinct reviews per submission, and will follow ICCV standards and policies. The accepted papers will be published in the ICCV proceedings. All paper submissions must adhere to the ICCV 2021 paper submission style, format, and length restrictions.

A5. Keynote Speakers

  1. Sebastiano Battiato, Professor, Department of Mathematics & Informatics, University of Catania, “COVID-19 Diagnosis by IA-based imaging technologies”.
  2.  Massimo Villari, Professor, Future Computing Research laboratory, University of Messina, “Neuro-Crying Analysis by IA-based imaging: children crying with neuro disorder”.


B. COV19D Competition

B1. Scope

COV19D Competition is based on a database of chest CT scan series that is manually annotated with respect to Covid-19/non-Covid-19 diagnosis. The database is split into training, validation and test partitions. The training and validation sets along with their corresponding annotations will be provided to the Competition participating teams to develop AI/ML/DL models for Covid-19 and non-Covid-19 prediction. Performance of the different approaches will be evaluated on the test set.

B2. Call for Participation

The participating teams will submit their Covid-19 predictions for the test dataset. The winner of the Competition will be selected based on the achieved performance, in terms of the ‘macro’ F1 score, on the test set.

There will be one Competition winning team. The top-3 performing teams are expected to contribute a paper describing their approach, methodology and results to our MIA Workshop. All other teams will be able to submit a paper describing their solutions and final results to the MIA Workshop. The accepted papers will be part of the ICCV 2021 proceedings. 

Regarding the database: It consists of about 5,000 CT scan series. Each chest CT scan series consists of a sequence of 2-D CT slices, the number of which is between 50 and 700. The research groups will be able to use any publicly available datasets as long as they report it in their submitted final paper. We will provide a white paper describing the Competition, the database used, as well as a baseline model and its results for comparison purposes.

In order to participate in the Competition, teams will need to register. At the end of the Competition, each team will have to send us: i) their predictions on the test set, ii) a link to a Github repository where their solution/source code will be stored, and iii) a link to an ArXiv paper with 2-6 pages describing their proposed methodology, data used and results. After that, the winner of the Competition will be announced and a leaderboard will be published. The winner and the two runner-ups in the Competition will be asked to also share their trained models so as to check out the validity of the approach.

B3. Important Dates

The timeline for the competition will be as follows:

  • May 3, 2021: Opening of the Competition; start of registration of research groups;  provision of training and validation datasets, of respective annotations and of the baseline approach
  • July 5, 2021: Final submission deadline (Results, Code and ArXiv paper)
  • July 6, 2021: Winners announcement
  • July 19, 2021: Final paper submission deadline
  • August 6, 2021: End of review period
  • August 10, 2021: Review decisions sent to authors; Notification of acceptance
  • August 17, 2021: Camera ready version deadline

B4. Submission Information

To participate, you need to register your team.
For this, please send us an email to: D.Kollias@greenwich.ac.uk
with the title “ICCV COV19D Competition: Team Registration”.
In this email include the following information:

Team Name
Team Members

There is no maximum number of participants in each team.

As a reply, you will receive the submission information and then access to the dataset’s images and annotations.

B5. Baseline Results (Validation Set)

The ‘macro’ F1 score on the validation set is 0.70.
