| Abstract(in English) | A method to reduce blocking artifacts and mosquito noise caused by Motion JPEG is proposed using a nonlinear digital filter and frame shift. Motion JPEG is widely used for video capture in PC and digital cameras, because it is realized with a simple system and can easily take out a frame as a still picture from video. But the efficiency of the data compression is not high enough, thus when the compression rate is high, the blocking artifacts and mosquito noise become outstanding. Authors proposed before a nonlinear digital filter, named as time and spatial ε-filter, to reduce such artifacts in motion-compensated inter-frame predictive DCT coding for video. This filter is effective for the predictive coding, but is not effective enough for Motion JPEG, because the artifacts appear in the same way at the same position in different frames and the time-domain filtering becomes meaningless. In this paper, a method to reduce the artifacts using the time and spatial ε-filter and frame shift is proposed. Here, the artifacts can be effectively reduced by changing their position by frame shift. Computer simulations show its high performance. |
