11. The system of claim 9 , wherein the spatial feature extractor includes: a block divider for dividing each of the normalized frames into image blocks with a predetermined size; a dominant color detector for detecting a dominant color from each of the divided image blocks; and an edge image detector for detecting an edge of each of the divided image blocks from an edge image of each of the divided image blocks.
