Abstract :
An effective approach in the design of two-dimensional notch FIR filters for image preprocessing useful in image communication is presented. The completely analytical design method is based on Zolotarev polynomials. Closed form formulas for the filter design are presented. One example demonstrates the design procedure. An application of the 2-D notch FIR filter for image preprocessing is presented.
