The polynomial matrix EVD (PEVD) is an extension of the conventional eigenvalue
decomposition (EVD) to polynomial matrices. The purpose of this article is to provide a …

Choice of filter bank in wavelet compression is a critical issue that affects image quality as
well as system design. Although regularity is sometimes used in filter evaluation, its success …

Image and Video Encryption provides a unified overview of techniques for encryption of
images and video data. This ranges from commercial applications like DVD or DVB to more …

The wavelet transform has become a cutting-edge technology in image compression
research. This article explains what wavelets are and provides a practical, nuts-and-bolts …

The theory of the orthogonal transform coder and methods for its optimal design have been
known for a long time. We derive a set of necessary and sufficient conditions for the coding …

An important issue in multiresolution analysis is that of optimal basis selection. An optimal P-
band perfect reconstruction filter bank (PRFB) is derived in this paper, which minimizes the …

The scientists and engineers of today are relentless in their continuing study and analysis of
the world about us from the microcosm to the macrocosm. A central purpose of this study is …

The emergence of wavelets has led to a convergence of linear expansion methods used in
signal processing and applied mathematics. In particular, subband coding methods and …

The problem of paraunitary (PU) filter bank design for subband coding has received
considerable attention in recent years, not least because of the energy preserving property …

Subband decomposition techniques have been extensively used for data coding and
analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to …
