1. A method for determining transitions in video content, the method comprising:

  • determining color layout information for a frame of the video content, the color layout information describing a distribution of color in the frame;

    determining edge distribution information for the frame, the edge distribution information describing a number of edges found in a plurality of regions of the frame;

    determining a set of color layout features from the color layout information regarding a color change within the frame;

    determining a set of edge distribution features from the edge distribution information in a set of regions in the plurality of regions, wherein the set of edge distribution features indicate a number of edges in the set of regions;

    determining whether the frame is classifiable as a solid color frame based on the set of color layout features and the set of edge distribution features; and

    when the frame is classifiable as the solid color frame, marking the solid color frame being a transition between a first type of video content and a second type of video content;

    wherein determining whether the frame is classifiable as a solid color frame comprises;

    determining when a first color layout feature in the set of color layout features indicates a luminance of the frame is below a first color layout threshold;

    determining when the number of edges in the set of edge distribution features for the plurality of regions is below a first edge threshold;

    determining when a second color layout feature in the set of color layout features indicates a change in luminance of the frame is above a second color layout threshold;

    determining when the number of edges in the set of edge distribution features for the set of regions is above a second edge threshold; and

    determining when the number of edges for regions not in the set of regions includes a number of bins including zero edges that is above a third edge threshold.
