This paper presents Edge-Guided (E-G), an optimized text preprocessing technique for compression purposes. It transforms the original text into a word net, which stores all relationships between adjoining words. A specific directed graph is proposed to model this transformation: words are stored in vertices, whereas edges represent word transitions. Thus, the word net has a text representation ...

Filtering is widely used in image and video processing for various applications among which EdgePreserving is the most popular one. Edge-preserving image smoothening has recently emerged as a valuable tool for a variety of applications such as denoising, tone mapping, non-photorealistic rendering in computer graphics and image processing. This can be achieved by a local filtering method such as...

In this paper a weighted guided image filter (WGIF) is being proposed incorporating an edge-aware weighting technique into the guided image filter (GIF). The WGIF preserves sharp edges as well as existing global filters, and the intricacy of the WGIF is O(N) for an image with N pixels which is almost the same as the GIF. As WGIF is simple, it has numerous applications in the fields of computati...

It is typical in edge detection applications to examine a single scale or to consider some space of scales in the image without knowing which scale is appropriate for each location in the image. However, many images contain a wide variation in the distance to the scene points, and thus objects of the same size can appear at greatly di ering scales in the image. We present a method where the sca...

The inner-surface damage of water conveyance tunnels is the main hidden danger that threatens their safety and leads to serious accidents. method based on principle acoustic reflection means inspecting water-conveyance tunnels. However, affected by tunnel environment equipment noise, obtained point cloud model inevitably suffers from which can produce erroneous results. Therefore, we proposed a...

‎let $g$ be a graph and $chi^{prime}_{aa}(g)$ denotes the minimum number of colors required for an‎ ‎acyclic edge coloring of $g$ in which no two adjacent vertices are incident to edges colored with the same set of colors‎. ‎we prove a general bound for $chi^{prime}_{aa}(gsquare h)$ for any two graphs $g$ and $h$‎. ‎we also determine‎ ‎exact value of this parameter for the cartesian product of ...

The following study provides new insight into how surface topography dictates directed collective epithelial cell sheet growth through the guidance of individual cell movement. Collective cell behavior of migrating human corneal limbal-epithelial cell sheets were studied on highly biocompatible flat and micro-patterned silk film surfaces. The silk film edge topography guided the migratory direc...

This paper introduces fast and effective fusing of images through merging of multiple images for creating a highly information fused image .Here the edge preserving smoothing filter is used as guided filter. The fusion criterion is to minimize the different error between the fused image and input image The proposed method is based on two scale decomposition of image into a detail layer capturin...

We develop a formalism, based on the mode expansion method, to describe the guided resonances and bound states in the continuum (BICs) in photonic crystal slabs with one-dimensional periodicity. This approach provides analytic insights to the formation mechanisms of these states: the guided resonances arise from the transverse Fabry-Pérot condition, and the divergence of the resonance lifetimes...

The novel ultrasonic NDT technique based on application of long range guided waves is proposed for detection of defects in a storage tank floor. The technique needs access only to the outer edge of the tank floor and do not require emptying and cleaning inside of the tank. The technique has been developed on the basis of the Lamb wave transmission tomography. The propagation of the guided waves...
