SURGICAL WORKFLOW AND ACTIVITY DETECTION BASED ON SURGICAL VIDEOS

摘要

One example method for detecting phases of a surgical procedure via video processing includes accessing a video of the surgical procedure and dividing the video into one or more blocks, each of the blocks containing one or more video frames. For each of the blocks, the method includes applying a prediction model on the video frames of the respective block to obtain a phase prediction for each of the video frames. The prediction model is configured to predict, for an input video frame, one of the plurality of phases of the surgical procedure. The method further includes generating an aggregated phase prediction for the respective block by aggregating the phase predictions of the video frames, and modifying the video of the surgical procedure to include an indication of a predicted phase of the respective block based on the aggregated phase prediction.
