Abstract
In this paper, the two dimensional (2D) IIR digital notch filter desig n problem is investigated. First, we develop a simple algebraic method for 2D IIR notch filter design. This approach not only has closed-for m transfer function but also satisfies bounded-input/bounded-output (B IBO) stability condition. Next, we apply the 2D notch filter to elimin ate sinusoidal/narrowband interferences superimposed on an image. Simu lation results are presented to demonstrate the effectiveness of this approach.
