Simultaneous replay of automatically synchronized videos of surgeries for feedback and visual assessment

The paper describes a method supporting visual assessment and training feedback for minimally invasive surgery. Assessment of surgical performance especially of training surgeons is an important, but delicate task. Simulators are currently far from incorporating the entire performance for assessment and feedback. Human teachers have to memorize all of the necessary facts in order to compare different performances for assessment. This work is meant to provide a supporting tool for a direct comparison of several surgeries. The system helps by displaying videos of the surgeries with a speed that is synchronized to the steps of the procedure rather than the time. Providing the view of each surgery at comparable points of the surgery allows for a direct comparison of performances without the cumbersome manual adjustment of the videos.
