Impulsive Noise Removal with an Adaptive Weighted Arithmetic Mean Operator for Any Noise Density
Many computer vision algorithms which are not robust to noise incorporate a noise removal stage in their workflow to avoid distortions in the final result. In the last decade, many filters for salt-and-pepper noise removal have been proposed.

A ROBUST OPEN-CLOSE SEQUENCE FILTER BASED ON MATHEMATICAL MORPHOLOGY [PDF]
A robust open close sequence filter based on mathematical morphology for high probability impulse noise removal is presented. First, an impulse noise detector using mathematical residues is proposed to identify pixels that are contaminated by the salt or pepper noise.

Dual-Band and Wideband Bandpass Filters Using Coupled Lines and Tri-Stepped Impedance Stubs
In this paper, two bandpass filters—one with a dual-band response and the other with a wideband response—were designed, implemented, and experimented with.

On the implementation and effectiveness of morphological close-open and open-close filters for topology optimization [PDF]
This note reconsiders the morphological close-open and open-close filters for topology optimization introduced in an earlier paper (Sigmund Struct Multidiscip Optim 33(4---5):401---424 (2007)). Close-open and open-close filters are defined as the sequential application of four dilation or erosion filters.

An Electroactive Filter with Tunable Porosity Based on Glycolated Polythiophene
The porosity of filters is typically fixed; thus, complex purification processes require application of multiple specialized filters. In contrast, smart filters with controllable and tunable properties enable dynamic separation in a single setup. Herein,

Resolved energy budget of superstructures in Rayleigh-B\'{e}nard convection [PDF]
Turbulent superstructures, i.e. large-scale flow structures in turbulent flows, play a crucial role in many geo- and astrophysical settings. In turbulent Rayleigh-B\'{e}nard convection, for example, horizontally extended coherent large-scale convection ...

AUTOMATED DETECTION OF LUNAR RIDGES BASED ON DEM DATA [PDF]
Wrinkle ridges are a common feature in the lunar maria and record subsequent contraction of mare infill. Automatic detection of wrinkle ridges is challenging because the ridges are of irregular shapes and many ridges have been eroded and/or degraded over

Efficient Online Tracking-by-Detection With Kalman Filter
Visual tracking of multiple objects in videos has a promisingly broad application in manufacturing, construction, traffic, logistics, etc., especially in large-scale applications where it is not feasible to attach markers to many objects for traditional,
