Flickering long-wavelength light appears more yellow than steady light of the same average intensity. The hue change is consistent with distortion of the visual signal at some nonlinear site (or sites) that produces temporal components not present in the original stimulus (known as distortion products). We extracted the temporal attenuation characteristics of the early (prenonlinearity) and lat...

We introduce and analyze a new class of nonlinear filters called permutation weighted order statistic (PWOS) filters. These filters extend the concept of weighted order statistic (WOS) filters, in which filter weights associated with the input samples are used to replicate the corresponding samples, and an order statistic is chosen as the filter output. PWOS filters replicate each input sample ...

The Kalman filter is a workhorse of dynamical modeling. But there are challenges when using the in environmental science: complexity processes, complicated and irregular nature many datasets, scale which may comprise thousands observations per time-step. We show how these can be met within filter, identifying some situations relatively easy to handle, such as datasets high-resolution time, hard...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...

Many discriminative correlation filter (DCF)-based methods have successfully leveraged the guidance for solving two problems (i.e., boundary effect and temporal filtering degradation) as a model prior to visual tracking. The intuitive motivation of these is control degeneration updating loss objective function with structural framework. While rely mostly on various regularization items, they al...
