Parametric Elliptically-Shaped Zero-Phase 2D IIR Filter Design
This paper proposes an analytical design method for a class of 2D IIR filters, namely elliptically-shaped zerophase filters. These also include orientation-selective filters with a narrow frequency response along a specified direction in the frequency plane. The approached filters are based on zero-phase low-pass 1D prototypes. We consider a maximally-flat filter with minimum errors in the pass...
متن کاملOn Lowpass and Highpass IIR Filters With an Adjustable Bandwidth
This paper deals with adjustable-bandwidth digital lowpass and highpass IIR filters obtained from a lowpass prototype filter via frequency transformations. Starting with adjustable-bandwidth filter specifications, including requirements on passband and stopband edges as well as on passband and stopband ripples, it is shown how to select the prototype filter and how to perform the frequency tran...
متن کاملDesign of multiplierless elliptic IIR filters
A new straightforward design of a special class of elliptic IIR lters is presented. The major goal is the complexity reduction of the realized digital lter. The multiplier coe cients are implemented with limited number of shift-and-add operations. This method is also called "multiplierless". Unlike classical design, a closed-form relations are derived giving relationships between the lter speci...
متن کاملNovel Design Method of Digital IIR Filters
A novel method of the IIR filter design using the genetic algorithm is described in the paper. Newly, a simplex direct search method is included to the algorithm to enable its faster convergence. The design procedure is implemented in the MATLAB program environment. The genetic algorithm applied is able to find a solution of the task successfully. Filter coefficients quantization process is inc...
متن کاملAnalytical Design and Applications of Double-Directional IIR Filters
Minimal user interaction in coronary artery centerline extraction is important for computer aided system in Coronary Artery Disease detection. However, manual seeding leads to error propagation most of the time. In this paper, we propose a neighbourhood search feedback mechanism in centerline tracking to overcome this problem. Two contributions from this paper are: (1) Seed Point Optimization w...
