Lapex: A new multimodal dataset for context recognition and practice assessment in laparoscopic surgery

The LapEx dataset contains 30 videos of sleeve gastrectomy surgeries performed by two surgeons. The videos were captured at 25 fps. Three annotation tasks were performed on the videos of the "dissection of fundus" surgical step : 1. Surgical activites were annotated with the quadruplet < actor , instrument , verb , target > 2. The quality of exposure was annotated with a value in [good, satisfying, unsatisfying] 3. Images were completely segmented with a labeling of visible tools and organs
