Abstract(in English)	This paper proposes a new method for designing variable 2-D digital filters with arbitrarily variable 2-D frequency responses. The design method simplifies the difficult variable filter design problem as the relatively easier one that only requires constant 2-D filter design and multi-dimensional (M-D) polynomial fitting. It includes the following steps. (1). Construct a complex M-D array by sampling the variable 2-D frequency response specification, and decompose the M-D array into the sum of products of 2-D complex arrays (matrices)and M-D real arrays. (2). Approximate the complex arrays by using constant 2-D digital filters, and fit the real arrays by using M-D polynomials. (3). Interconnect the constant 2-D filters and M-D polynomials to form a variable 2-D filter.
