This paper presents results of a comparative study of two possible hybrid filter topologies, comprised of a passive and active stage, which can be implemented in any general dc supply distribution system. The main filter task is to mitigate current dynamics in the dc distribution system in order to prolong the operational life of delicate dc supplies ...

A hybrid filter for image enhancement
Proceedings., International Conference on Image Processing, 2002We present a new hybrid filter design methodology. Our hybrid filter consists of a nonlinear impulsive noise filter and a fuzzy weighted linear filter. This hybrid filter can efficiently remove large amounts of mixed Gaussian and impulsive noise while preserving the image details. The performance and robust stability of the proposed filter are compared

This paper introduces a new generalized class of median-type filters which we call FIR-median hybrid (FMH) filters. The input signal x(n) is filtered with M linear phase FIR filters, and the output of the FMH filter is the median of the outputs of the FIR filters.

Summary: A new class of nonlinear filters, the so-called class of multidirectional infinite impulse response median hybrid filters, is presented and analyzed. The input signal is processed twice using a linear shift- invariant infinite impulse response filtering module: once with normal causality and a second time with inverted causality.

AbstractNarrow bandwidth bandstop filters or ‘notch filters’ are frequently required in both communication and electronic warfare systems. In the latter case the ability to switch into an ‘allpass’ state with a minimum level of loss and time delay distortion is vital. Furthermore, in both cases a level of 20‐30 dB rejection is normally required.

Cell Hybridization by Electrofusion on Filters
Analytical Biochemistry, 2002Electric field pulses induce permeabilization and associated fusogenicity in cell membranes. Electrofusion of cells is usually performed in two steps: the first is the creation of close intercellular contacts; the second is an application of electric pulses that induces membrane fusion.

A hybrid filter for program personalization
Proceedings ITCC 2003. International Conference on Information Technology: Coding and Computing, 2004The current exponential growth of DTV programs precipitates a need for new filtering techniques to provide program personalization for people. Several filtering methods, notably Boolean filtering and similarity-based filtering, have been proposed in information filtering.

Median-rational hybrid filters
Proceedings 1998 International Conference on Image Processing. ICIP98 (Cat. No.98CB36269), 2002We introduce a new class of nonlinear filters called median-rational hybrid filters (MRHF) based on rational functions (RF). The filter output is the result of a rational operation taking into account three sub-functions, such as two FIR or median sub-filters and one center weighted median filter (CWMF).

An In/Post-Loop Deblocking Filter With Hybrid Filtering Schedule
IEEE Transactions on Circuits and Systems for Video Technology, 2007In this paper, we propose a high-throughput deblocking filter to perform the in-loop or post-loop filtering process for different standard requirements. The performance improvement is very mild if we replace a post-loop filter with an in-loop filter. To alleviate this problem, we derive an integration-oriented algorithm that can be reconfigured as the ...

This chapter describes a standard method for the hybridization of labeled DNA probes to nucleic acids bound to a nylon matrix. Filters bearing bound nucleic acids produced by Northern blotting of RNA (Chapter 39), Southern blotting of DNA (Chapter 37), and slot blotting of DNA (Chapters 35) or RNA (Chapter 40) are hybridized to labeled probes using the
