Optimal decentralized Kalman filter and Lainiotis filter

Digital Signal Processing, 2013
A method to implement the optimal decentralized Kalman filter and the optimal decentralized Lainiotis filter is proposed; the method is based on the a priori determination of the optimal distribution of measurements into parallel processors, minimizing the computation time.

Robustness of optimal binary filters

Journal of Electronic Imaging, 1998
An optimal filter estimates an unobserved ideal image from an observed image. Optimality is with respect to some error criterion, which is mean absolute error for the binary images. Both the ideal and observed images are random sets and these are governed by parameterized probability laws.

Optimal filtering for multirate systems

IEEE Transactions on Circuits and Systems II: Express Briefs, 2005
For a multirate system where the output sampling is slower than the input updating, this brief aims at designing filters for fast state estimation in the H/sub 2/ and H/sub /spl infin// settings. Because of the multirate nature, linear matrix inequality solutions to the design problems involve a nonconvex constraint, which is numerically tackled by the

Optimal real correlation filters

Applied Optics, 1991
Expressions are derived for real filters that have a maximum correlation signal to noise ratio. Both continuous and discrete cases are treated and shown to have similar forms. The signal can be complex, and the case of a real signal is considered and related to previous results.

Optimal filtering in the subband domain

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
An analytical framework for the implementation of optimal filters in the multiresolution (i.e., subband) domain is presented. In particular, we concentrate on filter bank based on the notions of wavelets and wave-packets. We show how the notion of sparse estimation can lead to significant reduction in computational cost, with only a minor degradation ...

On optimal IFIR filter design

2004 IEEE International Symposium on Circuits and Systems (ISCAS), 2004
This paper presents an analytical method for the design of interpolated finite impulse response (IFIR) digital filters. The problem of determining the optimum "stretch factor" L is specifically addressed, as is the optimal determination of multiple stretch factors for generalized IFIR designs where the minimum number of multipliers is sought.

Optimal Queries in Information Filtering

2000
Information filtering has become an important component of modern information systems due to significant increase in its applications. The objective of an information filtering is to classify/categorize documents as they arrive into the system. In this paper, we investigate an information filtering method based on steepest descent induction algorithm ...
