Abstract: This paper proposes a 3-D filtering scheme which reduces temporal aliasing effectively and requires much less memory than conventional schemes in hardware implementation. Our 3-D filter is implemented in the form of a space-variant 2-D finite-duration impulse response (FIR) filter in the spatial domain with motion information. The filter requires only one frame and its motion vectors. The simulation result for the image sequence with constant motion informs explicitly that our filter has temporal de-aliasing property and 3-D band-limitation.<>
