2D 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...
متن کاملImage Reconstruction using a 2D M-channel Perfect Reconstruction Filter Bank with an Optimized Adaptive Interpolation Kernel
In this paper, we propose an image reconstruction method utilizing an optimized adaptive interpolation kernel along with a 2D M-channel perfect reconstruction filter bank(M-ch PR-FB) structure. In particular, the proposed approach leads to sharper reconstructed images than a direct conversion, still preserving high frequency components of the original image by employing the subband processing o...

متن کاملNoise robust oversampled linear phase perfect reconstruction filter bank with a lattice structure
An oversampled linear phase (LP) perfect reconstruction (PR) filter banks (FB) with a lattice structure involving the noise robust building block is presented. The structure is based on the generalized lapped pseudo-biorthogonal transform (GLPBT), which represents a large class of lapped transforms. Given an analysis bank of the GLPBT and a correlation matrix of noise, the proposed synthesis ba...
متن کاملLinear-phase perfect reconstruction filter bank: lattice structure, design, and application in image coding
A lattice structure for an -channel linear-phase perfect reconstruction filter bank (LPPRFB) based on the singular value decomposition (SVD) is introduced. The lattice can be proven to use a minimal number of delay elements and to completely span a large class of LPPRFB’s: All analysis and synthesis filters have the same FIR length, sharing the same center of symmetry. The lattice also structur...
