Image processing researchers commonly assert that "median filtering is better than linear filtering for removing noise in the presence of edges." Using a straightforward large-n decision-theory ...

This paper considers the problem of jointly decomposing a set of time series variables into cyclical and trend components, subject to sets of stochastic linear restrictions among these cyclical and ...

BALZERS, Liechtenstein--(BUSINESS WIRE)--The current SARS-CoV-2 pandemic has made it abundantly clear how important it is to determine analytical laboratory values quickly and accurately. However, ...

It appears that no particular approximate [nonlinear] filter is consistently better than any other, though . . . any nonlinear filter is better than a strictly linear one. 1 The Kalman filter is a ...

Delta Optical Thin Film has lifted the application range of variable filters to new levels by introducing a new powerful type of linear variable filter (LVF). Since Delta Optical Thin Film offered the ...
