A data filter is a device, algorithm, or process that removes some unwanted components or features from a data signal. The unwanted component may be random noise (perhaps from mixing turbulence or ...

Image processing has evolved into a cornerstone of scientific and industrial applications, spanning from medical imaging to autonomous vehicles. A critical aspect of this field is edge-preserving ...

We link optimal filtering for hidden Markov models to the notion of duality for Markov processes. We show that when the signal is dual to a process that has two components, one deterministic and one a ...

The filtering process used to remove sediment from beer and wine could contaminate drinks with potentially dangerous heavy metals such as arsenic, scientists have warned. Manufacturers often use ...
