SURGICAL TASK DATA DERIVATION FROM SURGICAL VIDEO DATA

Various of the disclosed embodiments are directed to systems and computer-implemented methods for determining surgical system events and/or kinematic data based upon surgical video data, such as video acquired at an endoscope. In some embodiments, derived data may be inferred from elements appearing in a graphical user interface (GUI) exclusively. Icons and text may be recognized in the GUI to infer event occurrences and tool actions. In some embodiments, derived data may additionally, or alternatively, be inferred from optical flow values derived from the video and by tracking tools entering and leaving the video field of view. Some embodiments include logic for reconciling data values derived from each of these approaches.
