A recursive weighted median (RWM) filter structure admitting negative weights is introduced.
Much like the sample median is analogous to the sample mean, the proposed class of RWM …

Publisher Summary Image enhancement tools are often classified into point operations and
spatial operations. Point operations include contrast stretching, noise clipping, histogram …

Weighted myriad smoothers have been proposed as a class of nonlinear filters for robust
non-Gaussian signal processing in impulsive noise environments. However, weighted …

A new edge-guided morphological filter is proposed to sharpen digital images. This is done
by detecting the positions of the edges and then applying a class of morphological filtering …

Optical proximity correction (OPC) methods are resolution enhancement techniques used
extensively in the semiconductor industry to improve the resolution and pattern fidelity of …

This paper presents an efficient video filtering scheme and its implementation in a field-
programmable logic device (FPLD). Since the proposed nonlinear, spatiotemporal filtering …

This paper introduces a novel nonlinear filtering structure: the linear combination of
weighted medians (LCWM). The proposed filtering scheme is modeled on the structure and …

En el tratamiento de imágenes que se apartan del modelo Gaussiano aditivo, en particular
aquellas que además exhiben una baja relación se nalruido o presentan ruido impulsivo, la …

A widely held view in the nonlinear signal processing community is that the class of stack
filters is robust. Although this is supported by extensive experimental evidence, no …

Statistical signal processing and communication theory have traditionally been dominated
by the Gaussian distribution model for the underlying random processes. However, a large …
