Filter Approximation Using Lattice Structure of 2D Non-separable Orthogonal Wavelet Filter Banks
نویسندگان
چکیده
In this paper, we present a method of approximating a given 2D filter using the orthogonal wavelet filter banks. Construction of 2D orthogonal wavelet filter banks is still an open problem. In this paper, a family of orthogonal wavelet filter banks based on 2D lattice structure are used to approximate the desirable filter. By virtue of this structure, we approximate the given filter step by step so that the complexity degree is largely reduced.

Constraints of Second-Order Vanishing Moments on Lattice Structures for Non-separable Orthogonal Symmetric Wavelets
In this paper, a design method of two-dimensional (2-D) orthogonal symmetric wavelets is proposed by using a lattice structure for multi-dimensional (M-D) linear-phase paraunitary filter banks (LPPUFB), which the authors have proposed as a previous work and then modified by Lu Gan et al. The derivation process for the constraints on the second-order vanishing moments is shown and some design ex...
متن کاملNew Design of Orthogonal Filter Banks Using the Cayley Transform
It is a challenging task to design orthogonal filter banks, especially multidimensional (MD) ones. In the onedimensional (1D) two-channel finite impulse response (FIR) filter bank case, several design methods exist. Among them, designs based on spectral factorizations (by Smith and Barnwell) and designs based on lattice factorizations (by Vaidyanathan and Hoang) are the most effective and widel...
متن کاملLattice structure for two-band perfect reconstruction filter banks using Pade approximation
We show how the Pad e table can be utilized to develop a new lattice structure for general two-channel bi-orthogonal perfect reconstruction (PR) lter banks. This is achieved through characterization of all two-channel bi-orthogonal PR lter banks. The parameter space found using this method is unique for each lter bank. Similarly to any other lattice structure, the PR property is achieved struct...
متن کاملOptimal design of high-performance separable wavelet filter banks for image coding
An optimization-based method is proposed for the design of high-performance separable wavelet filter banks for image coding. This method yields linear-phase perfect-reconstruction systems with high coding gain, good frequency selectivity, and certain prescribed vanishing-moment properties. Several filter banks designed with the proposed method are presented and shown to work extremely well for ...
متن کامل2D Four-Channel Perfect Reconstruction Filter Bank Realized with the 2D Lattice Filter Structure
In this paper, a novel orthogonal 2-D lattice structure is incorporated into the design of a nonseparable 2-D fourchannel perfect reconstruction filter bank. The proposed filter bank is obtained by using the polyphase decomposition technique which requires the design of an orthogonal 2-D lattice filter. Due to constraint of perfect reconstruction, each stage of this lattice filter bank is simpl...
