CholecInstanceSeg: A Tool Instance Segmentation Dataset for Laparoscopic Surgery

This paper introduces CholecInstanceSeg, the largest open-access dataset for surgical tool instance segmentation to date. It addresses key gaps in existing datasets by providing high-quality instance annotations for over 41,000 frames derived from clinical laparoscopic cholecystectomy procedures.

Visual representation of challenging annotation scenarios. Each image highlights a specific hard case: motion blur, smoke, soft tissue occlusion, tissue attachment, saturated lighting, instrument at the edge, reflection, instrument in fluid, low lighting, dirty lens, camera in port, and instrument far from the camera.
