Mapping between 300 clips in Task 2/3 and 21 videos in Task 1

[adit98]

Hi,

I was wondering if the training/validation/testing splits of the 300 clips used in tasks 2 and 3 correspond to the train/val/test splits of the 21 videos used in task 1. In other words, are the 170 clips of the Task 2 training set all taken from the 10 training videos of task 1, and similarly for val and test? Thanks!

Hi @adit98

Thanks for your question.

The data splits of train/val/test for Task 2/3 correspond to the videos in Task 1 as follows: 1-10/11-16/17-21. Details about the clip-video data mapping information can be found in the supplementary material.

Ok, if I understood correctly:

Task 1 Train/Val/Test: 1-10 / 11-14 / 15-21
Tasks 2 and 3 Train/Val/Test: 1-10 (Clips 1-170) / 11-16 (clips 171-227) / 17-21 (clips 228-300)

Would it be possible to see the metadata on the mapping between the frames of each clip and the frames of the originating video?

Yes, the dataset splitting is the same as we used in the paper.

We did not record the precise timestamps for Task 2/3 corresponding to the Task 1 original videos.
In the annotation file, we provide the mapping between each clip and the surgical phases in Task 1, which can be used as a rough reference if needed.
