CholecT50 (Cholecystectomy Action Triplet)
CholecT50 is a dataset of endoscopic videos of laparoscopic cholecystectomy surgery introduced to enable research on fine-grained action recognition in laparoscopic surgery. It is annotated with triplet information in the form of . The dataset is a collection of 50 videos consisting of 45 videos from the Cholec80 dataset and 5 videos from an in-house dataset of the same surgical procedure.
CholecT50 is an extension of CholecT40 with 10 additional videos and standardized classes.
CholecT45 is a subset of CholecT50 consisting of 45 videos from the Cholec80 dataset and first public release of CholecT50.
The following are the official variants of the dataset:
- 1. CholecT50 : the original version as used in the Rendezvous publication.
- ** 2.CholecT50 (challenge)** : the variant used in CholecTriplet challenge.
- ** 3. CholecT50 (cross-val)**: official cross validation split of CholecT50.
- ** 4. CholecT45 (cross-val)**: official cross validation split of CholecT45.
- ** 5. CholecT40** : the original version of CholecT40 as used in Tripnet publication.
The complete dataset split information is given here.

8 shown of 8 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 32. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
