Real-Time 3D Tracking of Laparoscopy Training Instruments for Assessment and Feedback

Assessment of minimally invasive surgical skills is a non-trivial task, usually requiring the presence and time of expert observers, including subjectivity and requiring special and expensive equipment and software. Although there are virtual simulators that provide self-assessment features, they ar...
