Processing arbitrary-length signals with MDFT filter banks

1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002
In this paper, methods for processing arbitrary-length input signals with MDFT filter banks are presented. The MDFT filter bank can be regarded as the most general type of a special class of filter banks. These filter banks have linear phase analysis filters, but different centers of symmetry due to subsampling with and without a phase shift.

Neural filtering method for stationary signal processes

Artificial Life and Robotics, 1997
In this paper a new method of neural filtering using artificial neural network systems is presented for the filtering problems of linear and nonlinear, stationary and nonstationary stochastic signals. The neural filter (denoted neurofilter) developed in this paper has either finite impulse response (FIR) structure or infinite impulse response (IIR ...

Adaptive filters for multichannel signal processing

1998 IEEE Symposium on Advances in Digital Filtering and Signal Processing. Symposium Proceedings (Cat. No.98EX185), 2002
The amount of research published to date indicates an increasing interest in the areas of multichannel signal processing. The availability of a wide set of multichannel information sources in application areas, such as color image processing, multispectral remote sensing imagery, biomedicine, robotics and industrial inspection have stimulated a renewed

Optical signal processing with illumination-encoded filters

Computer Vision and Image Understanding, 2011
Recently, computer vision researchers have shown that orthogonal functions and computational techniques from the signal processing framework can be mapped directly into the scene using projector-camera systems. These scene-space signal processing algorithms are achieved with illumination-encoded functions as primitives and computations derived from ...

Processing visual signals with nonlinear spatial filters

Journal of Mathematical Biology, 1977
The properties of nonlinear spatial filters as a major part of the peripheral nervous system are investigated with respect to processing of two types of signals: a deterministic stepfunction and Graussian noise. The nonlinearity of the nerve cell is treated as a threshold element.

Signal Processing for Active Power Filters

2011
The paper describes special active power filter solution. There are given control algorithms and methods for the filter current regulation. Firstly, there is described power part structure of the filter with the resonant converter and general conception structure of the filter.

Single-frequency filter for signal processing

Novosti nauki Kazahstana
Modern methods of band-stop filtering are sensitive to the influence of high-frequency single-frequency interference, which significantly distorts the shape of the informative signal. The noted feature is leveled by the system of narrow-band high-Q band-stop filtering developed in the article.
