Abstract The existing methods for designing two-dimensional digital filters are outlined anda new method——composite method——is proposed. This method has following advan-tages: (1) its computation cost is low; (2) it is easy to acquire lineur phase performance; ( 3 ) it is conient to be generalized to multi-dimensional ones; and so on. Some expe-rimental results show that it can get better results with lower computation cost than two-dimensional window method. Therefore, it applies no only to image processing systems or other computer systems for programming software, but also to some reseach work that involve two-dimensional or multi-dinensional digital filtering.
