REAL-colon dataset

The REAL (Real-world multi-center Endoscopy Annotated video Library) - colon dataset is composed of 60 recordings of real-world colonoscopies. The recordings comes from 4 different clinical studies (001 to 004), each contributing with 15 videos. For each patient/video, several clinical variables have been collected, including endoscope brand, bowel cleanliness score (BBPS), number of surgically removed colon lesions, etc. Each removed lesion has been annotated with a bounding box in each video frame where it appeared by trained labelers, supervised by expert gastroenterologists. Polyp information including histology, size and anatomical site has been recorded.

Key stats:

- 60 recordings, 15 for each of the 4 centers

- 2757723 total frames

- 132 removed colorectal polyps

- 351264 bounding box annotations

The dataset is composed of the following files:

- 60 compressed folders named `{SSS}-{VVV}_frames` with the frames from each recording

- 60 compressed folders named `{SSS}-{VVV}_annotation` with the annotations from each recordings

- video_info.csv file, a file with the metadata for each video

- lesion_info.csv, a file with the metadata for each lesion

- dataset_description.md, a readme file with information about the dataset
