The results of research on rank filters are presen ted. The relationship of rank filters with other filters is briefly discussed. The main properties of rank filters are listed and an explanation is given for these properties. Several software and hardware implementations of the filter are described. Major applications to image processing are discussed, including noise smoothing, cluster detect...

The local electric field enhancement at various regions of an individual nanometre-thin gold mesotriangle has been demonstrated both numerically and experimentally. This work provides, for the first time, direct experimental evidence of localized enhancement of Raman signals at three edges of nanometre-thin gold mesotriangles at single particle level, using Raman microscopy. Raman images were c...

Light harvesting enhancement by slow photons in photonic crystal catalysts or dye-sensitized solar cells is a promising approach for increasing the efficiency of photoreactions. This structural effect is exploited in inverse opal TiO2 photocatalysts by tuning the red edge of the photonic band gap to the TiO2 electronic excitation band edge. In spite of many experimental demonstrations, the slow...

Edge detection serves as a pre-processing step for many image processing algorithms such as image enhancement, image segmentation, tracking and image/video coding. The edge detection is one of the key stages in image processing and object recognition. This paper present a Canny edge detection algorithm that results in significantly reduced memory requirements, decreased latency and increased th...

In 5G, multi-access edge computing enables the applications to be offloaded near-end servers for faster response. According 3GPP standards, users in 5G are separated into many types, e.g., vehicles, AR/VR, IoT devices, etc. Specifically, high-priority traffic can preempt resources guarantee service quality. However, even if a is transmitted with low priority, its latency requirement much lower ...

In this article CuO/water nanofluid was synthesized by using polyvinylpyrolidone (PVP) as the dispersant.  Thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. To study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different pH values and PVP surfactant concentrations; also thermal conductivity...

Background: Economic burden due to premature mortalities is significant both on health system and on the society as a whole. This study aimed to determine the productivity costs and years of potential life lost associated with five leading causes of death in Iran from 2006 to 2010.   Methods: Data on mortality by sex and age-groups due to five main leading causes of death   (m...

Image enhancement is useful when the details in an image are lost due to various reasons. I t is common to subtract a mask from a given image to enhance the details. The trick is how to obtain a good mask. We describe here how an edge-preserving filter can be used to generate a mask which is smooth over areas with fine details, yet preserving most of the edges. Experiments with real images show...
