Abstract :
A two-dimensional adaptive IIR filter is designed with fixed poles, to ensure stability and reduce computation. The resulting structure is a parallel filter bank of separable, two-dimensional, second-order Butterworth filters. Each filter in the bank has a single adaptive numerator term (gain). The fixed poles force each filter in the bank to occupy a fixed region of frequency space
