چکیده
Novel approach in the design of 2−D extremely narrow bandstop FIR filters is presented. The completely analytical design method is based on the 1−D optimal bandstop FIR filters. The 1−D FIR optimal bandstop filters are based on Zolotarev polynomial. Closed form formulas for the design of the filters are presented. One example demonstrates the design procedure. One application of the 2−D narrow bandstop FIR filter for image enhancement is presented.

Analytical Design of Zero-phase Circular 2d Fir Filters
This paper proposes a simple and efficient analytical design method for 2D non-recursive filters with circularlysymmetric and zero-phase frequency response. The design is achieved in the frequency domain and is based on prototype filters of two types: maximally-flat and Gaussian-shaped. The 2D FIR filter transfer function results directly in factorized form. Two types of 2D circular filters wil...
متن کاملDesign of sharp FIR bandstop filters using quadrature masking filters
A novel computationally highly e cient realization of sharp symmetrical bandstop FIR lter is proposed. The new structure is derived using the frequency-response-masking technique, where the bandedge-shaping lter is derived from half-band lter by substituting each delay of the half-band lter by M delays. The masking lters are unconventional. They are quadrature lters derived from linear combinat...

متن کاملBiomedical Image Denoising Based on Hybrid Optimization Algorithm and Sequential Filters
Background: Nowadays, image de-noising plays a very important role in medical analysis applications and pre-processing step. Many filters were designed for image processing, assuming a specific noise distribution, so the images which are acquired by different medical imaging modalities must be out of the noise. Objectives: This study has focused on the sequence filters which are selected ...
