The distributed Karhunen-Loeve transform

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The Karhunen-Loeve transform (KLT) is a key element of many signal processing tasks, including approximation, compression, and classification. Many recent applications involve {\em distributed} signal processing where it is not generally possible to apply ...

Highly sensitive Hall magnetic sensor microsystem in CMOS technology

Maher Kayal, Radivoje Popovic

A highly sensitive magnetic sensor microsystem based on a flail device is presented. This microsystem consists of a Hall device improved by an integrated magnetic concentrator and new circuit architecture for the signal processing. It provides an amplifica ...

The distributed Karhunen-Loeve transform

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The Karhunen-Loeve transform is a key element of many signal processing tasks, including classification and compression. In this paper, we consider distributed signal processing scenarios with limited communication between correlated sources, and we invest ...

High-order balanced multiwavelets: theory, factorization, and design

Martin Vetterli, Jérôme Lebrun

This correspondence deals with multiwavelets, which are a recent generalization of wavelets in the context of time-varying filter banks and with their applications to signal processing and especially com- pression. By their inherent structure, multiwavelet ...

Linear Estimation

Ali H. Sayed

This textbook is intended for a graduate-level course and assumes familiarity with basic concepts from matrix theory, linear algebra, and linear system theory. Six appendices at the end of the book provide the reader with enough background and review mater ...

Fast updating of structured linear systems of equations with applications in adaptive filtering

Ali H. Sayed

Linear systems of equations with structured coefficient matrices arise in several applications in signal processing and communications. In this paper we develop fast algorithms for updating the solutions of such systems when the coefficient matrices underg ...

A computer-based method to quantify the classic pattern of choroidal neovascularization in order to monitor photodynamic therapy

Hubert van den Bergh

Photodynamic therapy (PDT) is a new treatment modality which relies on a nonthermal light exposure of choroidal neovascularization (CNV) which has accumulated a photosensitizer, to produce a photochemical thrombosis. The aim of the present study was to dev ...

Balanced MultiWavelets - Theory and Design

Martin Vetterli, Jérôme Lebrun

This paper deals with multiwavelets which are a recent generalization of wavelets in the context of multirate filter banks and with their applications to signal processing and especially compression. By their inherent structure, multiwavelets are fit for p ...

Consistent Signal Reconstruction and Convex Coding

Martin Vetterli

The ﬁeld of signal processing has known tremendous progress with the development of digital signal processing. The ﬁrst foundation of digital signal processing is due to Shannon's sampling theorem which shows that any bandlimited analog signal can... ...

Multiprocessor performances for dynamic programming

Roger Hersch

A new generation of microprocessors called transputers provide support for multiprocessing and communications. This paper compares performances obtained with different processors (68000 μP, signal processors, transputers) in single and multiprocessor co ...
