Cholecystectomy Action Triplet Dataset

CholecT50 is a dataset of endoscopic videos of laparoscopic cholecystectomy surgery introduced to enable research on fine-grained action recognition in laparoscopic surgery. The videos are collected in Strasbourg, France. The images are extracted at 1 fps from the videos and annotated with triplet information about surgical actions in the format of <instrument, verb, target>. The phase labels are also provided. Spatial annotations in the form of bounding boxes over the instrument tips are provided for 5 videos. The box-triplet matching labels are also provided for all bounding box annotations. The dataset is a collection of 50 videos consisting of 45 videos from the Cholec80 [1] dataset and 5 videos from the superset in-house Cholec120 [6] dataset of the same surgical procedure.

CholecT40 [2] is the first effort of creating surgical action triplet dataset consisting of 40 videos. CholecT50 [3] is an extension of CholecT40 with 10 additional videos and standardized classes.

CholecT45 [3] is a subset of CholecT50 consisting of 45 videos from the Cholec80 dataset and first public release of CholecT50. CholecT50 is the super set of CholecT45 and CholecT40 datasets.

Dataset Examples

Some example images with overlay of their labels.

Dataset Variants

The following are the official variants of the dataset:

1. CholecT50 (cross-val): the official cross validation split of CholecT50 [3]. (recommended)
2. CholecT50 (challenge) : the variant used in CholecTriplet challenges [4, 5] (recommended).
3. CholecT50 : the original version as used in the Rendezvous publication [3].
4. CholecT45 (cross-val): the official cross validation split of CholecT45 [3].
5. CholecT40 : the original version of CholecT40 as used in Tripnet publication [2].

For research purposes, we recommend the use of the CholecT50 (cross-val) version because it is complete and supports the evaluation of all the 100 triplet classes via k-fold cross-validation. Researchers can additionally use the CholecT50 (challenge) version to compare with the results presented at the CholecTriplet challenges.

We have provided bechmark results of baseline models and show how they compare across the above listed versions of the datasets in [6].
