Multidimensional matched filters
Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002This paper is concerned with the design of m-D (multidimensional) matched filters. First, the basic stochastic signal concepts are extended to the m-D case. Among these concepts are the correlation matrix, the Fourier transform, the power spectral density and the transmission of an m-D signal through an m-D linear system.

2014 22nd Telecommunications Forum Telfor (TELFOR), 2014
Crystal oscillators and filters are still very important devices in modern telecommunication and measurement equipment. Quartz crystal units are basic elements for those oscillators and filters, due to their extremely stable resonant frequency and Q-factor. Matched crystal filters are consisted of filter sections with the same phase characteristics. In

Matched filters in human vision
Biological Cybernetics, 1976The technique of subthreshold addition of sinusoidal gratings was used to analyse the visual system of man during the perception of edges, lines, and bars. The experimentally obtained sensitivity function varies in close relationship to the test pattern, and can be factorized into the conjugate complex spectrum of the test pattern at threshold and a ...

Fifth ASSP Workshop on Spectrum Estimation and Modeling, 1990
Many signal processing problems can be reduced to the research of an optimal filter minimizing a quadratic criterion of power under various constraints. In spite of the variety of these problems, as well as of their solutions, there exists a unity between them, which leads to their consideration under a unified framework called matched filtering. After

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2010
A novel chaotic oscillator is shown to admit an exact analytic solution and a simple matched filter. The oscillator is a hybrid dynamical system including both a differential equation and a discrete switching condition. The analytic solution is written as a linear convolution of a symbol sequence and a fixed basis function, similar to that of ...

Matched Filters for Bin Picking
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1984Currently, a major difficulty for the widespread use of robots in assembly and material handling comes from the necessity of feeding accurately positioned workpieces to robots. ``Bin picking'' techniques help reduce this constraint. This paper presents the application of matched filters for enabling robots with vision to acquire workpieces randomly ...

Stereo Matching Using Tree Filtering
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2015Matching cost aggregation is one of the oldest and still popular methods for stereo correspondence. While effective and efficient, cost aggregation methods typically aggregate the matching cost by summing/averaging over a user-specified, local support region.
