      Implemented a new edge detection video filter · 5025bc4e
      Odd-Arild Kristensen authored
      The edge detection filter uses the Sobel operator to detect and highlight
      edges in a frame. In order to successfully detect an edge, the image must
      first be converted to gray scale (because Sobel is a gray scale operator) and
      then have a slight Gaussian blur applied to it. We do this because Sobel is a
      noisy operator and the Gaussian blur reduces this noise.
