bstract. We present an order-statistics-based vector filter for the emoval of impulsive noise from color images. The filter preserves he edges and fine image details by switching between the identity no filtering) operation and the vector median filter operation based n the robust univariate median operator. Experiments on a diverse et of images and comparisons with state of the art filters sho...

In this paper, we introduce the value-and-criterion filter structure and give an example of a filter with the structure. The value-and-criterion filter structure is based on morphological opening (or closing), which is actually two filters applied sequentially: the first assigns values based on the original image values, and the second assigns values based on the results of the first. The value...

the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...

The Southern Photometric Local Universe Survey (S-PLUS) is an ongoing survey of $\sim$9300 deg$^2$ in the southern sky a 12-band photometric system. This paper presents second data release (DR2) S-PLUS, consisting 514 tiles covering area 950 deg$^2$. has been fully calibrated using new calibration technique suitable for generation wide-field multi-filter surveys. consists $\chi^2$ minimisation ...

This paper presents a compact bandpass filter with stopband and high attenuation by using multilayer folded broadside-coupled quarter-wavelength stripline resonators in a low-temperature co-fired ceramic (LTCC) substrate. The proposed bandpass filter centered at 1.1 GHz with a fractional bandwith of 4.5 % shows the first spurious frequency at 3.8 times the center frequency. In comparison to the...

In this paper, a highly-effective parallel filter for video denoising is presented. The filter is designed using a skeletal approach, and has been implemented by way of the FastFlow parallel programming library. As a result of its high-level design, it is possible to run the filter seamlessly on a multi-core machine, on GPGPU(s), or on both. The design and implementation of the filter are discu...

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 twomechanisms s...
