1. A system for processing a raw video stream, comprising:

  • a threshold detection stage comprising integrated circuitry configured to determine if a current frame of the video stream is sufficiently different from a previous frame of the video stream, and in response to the current frame not being sufficiently different than the previous frame, the threshold detection stage is further configured to stop further processing of the current frame by a subsequent stage; and

    a target presence stage comprising integrated circuitry configured to determine if the current frame includes skin tone colored pixels, and in response to the current frame not including skin tone colored pixels, the target presence stage is further configured to stop further processing of the current frame by a subsequent stage.
