Quaternion Multipliers Based Paraunitary Filter Banks for Transform Image Coding with Fixed Point Arithmetic Constraints
نویسندگان
چکیده
In this work, we have introduced a systematic design of the integerto-integer invertible quaternionic multiplier based on a generalized block-lifting structure using two alternative techniques: CORDIC architectures and distributed arithmetic (DA) as a block of M -band linear phase paraunitary filter banks LP Q-PUFB for the lossless-tolossy (L2L) image coding. The low latency separable image processing in real-time is implemented on the Xilinx Zynq.

Quaternionic Lattice Structures for Four-Channel Paraunitary Filter Banks
A novel approach to the design and implementation of four-channel paraunitary filter banks is presented. It utilizes hypercomplex number theory, which has not yet been employed in these areas. Namely, quaternion multipliers are presented as alternative paraunitary building blocks, which can be regarded as generalizations of Givens (planar) rotations. The corresponding quaternionic lattice struc...
متن کاملM-Channel Paraunitary Filter Banks Based on Direct Lifting Structure of Building Block and Its Inverse Transform for Lossless-to-Lossy Image Coding
This paper presents a paraunitary filter bank (PUFB) based on a direct lifting structure of a building block and its inverse transform for lossless-to-lossy image coding. Although the conventional liftingbased filter banks (LBFBs), which are constructed by lifting structures with integer coefficients and rounding operations, suffer from degradation of coding performance due to much rounding err...
متن کاملOrthonormal and biorthonormal filter banks as convolvers, and convolutional coding gain
A maximally decimated filter bank system (with possibly unequal decimation ratios in the subbands) can be regarded as a generalization of the short-time Fourier transformer. In fact, it is known that such a “filter bank transformer” is closely related to the wavelet transformation. A natural question that arises when we conceptually pass from the traditional Fourier transformer to the filter ba...
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 کاملA Split-Radix DCT Base Structure for Linear Phase Paraunitary Filter Banks
In this study, base on traditional lapped transform’s properties, inherit from some of the special characteristic properties of discrete cosine transform, trigonometric identities and the structure of linear phase filter banks. We present some theoretic properties in the generalized structure of linear phase paraunitary filter bank and build some examples corresponding to these properties. Thes...
