Motivations and objectives:   

The Operating Room (OR) is a high-tech environment that strongly relies on electronic devices, information systems and video equipment, all of which exchange, process or display signals containing key data about the underlying surgical process. In spite of their potential utility in contributing to the development of intelligent applications for the OR, currently these signals are being used solely for the immediate performance of the surgery. The fundamental idea behind our research is the fact that automatically recording, processing and analyzing the large amount of multi-modal surgical signals available in the OR, an endeavor largely unattempted so far, can lead to new assistance and decision support tools for surgeons and surgical staff.


Consequently, the research group on Computational Modeling and Analysis of Medical Activities aims at developing a multi-sensor data acquisition system for the operating room (OR) as well as devising novel methods to perceive, model and analyze surgical activities. These methods will be used to design a new generation of context-aware assistance systems for the OR that can help the surgical team with performing routine tasks and also enable them to better process and visualize the large amount of information generated during a surgical procedure.

Clinical tracking

Our research lies at the intersection of computer vision, medical robotics, augmented reality and machine learning. We seek in particular to leverage the large amount of data collected from medical devices and sensors used in a wide variety of surgical procedures to develop new algorithms and solutions for activity recognition and modeling. 

Surgical database analysis

A first application of our research is the monitoring of radiation during image-guided interventions to address the increased exposure of surgical staff to X-rays generated by imaging devices. This work is being carried out in collaboration with Strasbourg’s University Hospital and the IHU MixSurg institute.

A second application (video) is the development of tools to automatically process endoscopic surgeries for real-time safety monitoring, video database indexing and surgical education. This work is being carried out in collaboration with Strasbourg’s University Hospital, the IRCAD and the IHU MixSurg institute.

Main results and on-going work  

All results and on going work are available on the dedicated CAMMA website  via the several presented videos.

Our team is collaborating with the University Hospital of Strasbourg, IHU Strasbourg and IRCAD to build datasets for various medical recognition tasks which you can consult on CAMMA Website / Datasets.
