4. The machine-implemented method of claim 1 , wherein the step of extracting temporal attribute includes the steps of: dividing each of the normalized frames into image blocks with a predetermined size; detecting a dominant color from each of the divided image blocks; and detecting an edge from an edge image of each of the divided image blocks.
5. The machine-implemented method of claim 4 , wherein the edge is obtained by projecting the edge image in horizontal and vertical directions, or generating a histogram based on the pattern of the edge image.
