1. A method for detecting video frame types with median filtering, comprising steps of:

  • inputting pixels in a frame into a processor in order;

    calculating comb factor values of the pixels in the frame with a function;

    proceeding median filtering step to determine the comb factor value of each pixel;

    adding 1 to a counter if the pixel is comb factor;

    keeping the counter unchanged if the pixel is not comb factor;

    determining frame types according to the counter value and counter threshold value; and

    ending the detection flow.
