We have released a training dataset for each sub-challenge which can be downloaded on the sub-challenge webpage. A further dataset will be released at the end of July. Test data on which participants will be evaluated will be released in the middle of August. Please note that registration is required for each sub-challenge before data can be downloaded.
Additionally Intuitive Surgical is providing a $1000 prize for the winner of each sub-challenge.
Please email me directly if you have any questions or issues downloading the data.
