System and method for intraoperative video processing

A monitoring system for providing visual enhancements during a medical procedure, the system comprising:

• a sensor for capturing visual information of a site during the medical procedure in real time, the sensor being a camera and the visual information being a video of a field-of-view (FOV) of the site during the medical procedure, the visual information comprising current visual information as a current frame of the video taken at a first point in time during the medical procedure;
• a memory for storing at least a portion of the visual information as stored visual information, the stored visual information having been captured at a second point in time during the medical procedure prior to the first point in time, the stored visual information being one or more past frames of the video;
• a display for displaying the current visual information;
• and
• a processor coupled to receive the current and stored visual information from the sensor and the memory, and coupled to transmit output data for display on the display, the processor being configured to:
• identify and compare a feature of interest in the current visual information at the first point in time and the stored visual information at the second point in time;
• generate feedback data associated with the feature of interest using the current visual information and the stored visual information;
• and
• cause the display to display a virtual representation of the feedback data overlaid on the current visual information.
