摘要:
The rational approximation of two-dimensional (2D) digital filters in the spatial domain is examined. Non-iterative methods are presented for finding 2D recursive digital filters to approximate, in some sense, a desired 2D pulse response over a finite area. The methods require only linear calculations and they are quite straight forward. Two examples are given to illustrate the utility of the presented techniques.
