A fundamental building block of any computer-assisted interventions (CAI) is the ability to automatically understand what the surgeons are performing throughout the surgery. In other words, recognizing the surgical activities being performed or the tools being used by the surgeon can be deemed as an essential steps toward CAI. The main motivation for these tasks is to design efficient solutions for surgical workflow analysis. The CATARACTS dataset was proposed in this context. This dataset consists of 50 cataract surgery.
The dataset consists of 50 videos of cataract surgeries performed in Brest University Hospital. Patients were 61 years old on average (minimum: 23,maximum: 83,standard deviation: 10). Each surgery was recorded in two videos: the microscope video and the surgical tray video. The frame definition was 1920x1080 pixels (full HD resolution) for both types of videos. The frame rate was approximately 30 frames per second for the tool-tissue interaction videos and 50 frames per second for the surgical tray videos. Microscope videos had a duration of 10 minutes and 56 s on average (minimum: 6 minutes 23 s, maximum: 40 minutes 34 s, standard deviation:6 minutes 5 s). Surgical tray videos had a duration of 11 minutes and 3 s on average (minimum: 6 minutes 30 s, maximum: 40 minutes 48 s, standard deviation: 6 minutes 3 s). In total, more than nine hours of surgery (for each video type) have been video recorded. For more details about the dataset and the different tasks proposed, please refer to the links provided in the abstract.
Please note that the evaluation scripts (for the microscope test set) used in the challenges are available now. For CATARACTS 2018, in addition to the videos, we provide the images (images.zip) used in the challenge and the ground truth.
