N2 - This paper proposes an efficient frequency domain design method of three-dimensional (3-D) digital filters. The proposed method decomposes a given 3-D magnitude specification into 1-D magnitude specifications with small error. In order to design 3-D digital filters applicable to real-time video signal processing, this paper presents a novel approach to approximation of "negative" magnitude specifications given by the decomposition with causal IIR, filters in temporal direction and with linear phase non-causal IIR filters in spatial directions.
