TopCoW 2024 Challenge

Last year, TopCoW 2023 welcomed over 140 registered participants from four continents, and 20 teams successfully made a submission to our challenge. We presented the results and gave out small prizes to winning teams in Vancouver during the challenge event on October 12th at MICCAI 2023.

And now we are back for Season 2!

In the new 2024 edition of TopCoW, we release more training data, expand the test set, and introduce new tasks!

Here is what's new in 2024:

More Data

We increase both the training data and test data size. In particular, we double the test set for benchmarking and make it multi-center.

  • 39% increase in training data from 90 to 125 pairs of CTA and MRA
  • Double the online test data from 35 to 70 pairs (and maybe more!)
  • Additional multi-center test data
  • A new and more open data usage license
  • 👉 Our Data page has more details!
Two New Tasks

On top of the multi-class segmentation task continued from last year, we introduce two new tasks in 2024: CoW object detection and CoW graph classification. The two new tasks are closely related to our theme of CoW topological segmentation.

  • CoW object detection with 3D bounding box annotations
  • CoW graph classification with edge list annotations
  • Potential integration of three CoW tasks to help solve one another
  • 👉 Go to our Tasks page to find out more!
Updated Labels

We updated mask and bounding box labels for some of the 2023 data, both for training and the test data.

  • Corrected Betti-0 issues in mask labels for 19 cases from 2023 data
  • Refined CoW ROI 3D bounding box labels

TopCoW in Research
