• Title: Know your sensORs $\unicode{x2013}$ A Modality Study For Surgical Action Classification
• Authors: Lennart Bastian and Tobias Czempiel and Christian Heiliger and Konrad Karcz and Ulrich Eck and Benjamin Busam and Nassir Navab
• Abstract summary: The medical community seeks to leverage this wealth of data to develop automated methods to advance interventional care, lower costs, and improve patient outcomes. Existing datasets from OR room cameras are thus far limited in size or modalities acquired, leaving it unclear which sensor modalities are best suited for tasks such as recognizing surgical action from videos. This study demonstrates that surgical action recognition performance can vary depending on the image modalities used.

• Abstract: The surgical operating room (OR) presents many opportunities for automation and optimization. Videos from various sources in the OR are becoming increasingly available. The medical community seeks to leverage this wealth of data to develop automated methods to advance interventional care, lower costs, and improve overall patient outcomes. Existing datasets from OR room cameras are thus far limited in size or modalities acquired, leaving it unclear which sensor modalities are best suited for tasks such as recognizing surgical action from videos. This study demonstrates that surgical action recognition performance can vary depending on the image modalities used. We perform a methodical analysis on several commonly available sensor modalities, presenting two fusion approaches that improve classification performance. The analyses are carried out on a set of multi-view RGB-D video recordings of 18 laparoscopic procedures.
