SDP design procedure for energy compaction IIR filters
ABSTRACT In this paper we present a design method for optimal energy compaction IIR filters, where the numerator and denominator may have different degrees. The design is performed via iterative relaxations, where the numerator is optimized given the denominator, followed by optimization of denominator given the numerator. The two optimization problems involved are solved using semidefinite pro...
متن کاملDesign of 2-d Fan Filters with 5x5 Filteringmasks
In digital image processing, filtering tasks are typically implemented using filtering masks of very small sizes, for instance, 3x3, 5x5, or 7x7. The choice of filtering coefficients are usually heuristic, without rigorous mathematical derivation. In this work, we propose a constrained least-squared (LS) error approach to design 5x5 image filtering masks, which have moderate degrees of freedom....
متن کاملDesign of 2-D Half-Band Filters and Fan Filters Using 1-D One-Band Filters by GA Approach
This paper reveals that there exists a closed relationship between 2-D half-band filters and fan filters. It is also found that the complex conventional 2-D design methods can be replaced by the design of 1D filters only for design both filters. Furthermore, an effective GA approach is proposed for designing FIR digital filters. By minimizing a quadratic measure of the error in the frequency ba...
متن کاملOn SOCP/SDP Formulation of the Extended Trust Region Subproblem
We consider the extended trust region subproblem (eTRS) as the minimization of an indefinite quadratic function subject to the intersection of unit ball with a single linear inequality constraint. Using a variation of the S-Lemma, we derive the necessary and sufficient optimality conditions for eTRS. Then, an OCP/SDP formulation is introduced for the problem. Finally, several illustrative examp...
متن کاملA New Design Approach for Recursive Diamond-Shaped Filters
This paper proposes a new design method for two-dimensional diamond-shaped IIR filters. The design starts from a desired 1D prototype filter, to which a frequency transformation is applied, which leads to the 2D filter with desired shape. The frequency transformation is derived by specifying the filter shape in polar coordinates in the frequency plane. The designed filters also have the useful ...
