Whether you just want to take a peek of a remote computer status, or you want to install the latest version of a software on several workstations, you can do all of this from your computer. The networks are growing, the time spent administering the workstations increases and the number of repetitive tasks is going sky high. But here comes MESH to take that load off your shoulders. And because o...

OF THE DISSERTATION Multi-hop Routing for Wireless Mesh Networks

Polygonal meshes are used in many application scenarios. Often the generated meshes are too complex not allowing proper interaction, visualization or transmission through a network. To tackle this problem, simplification methods can be used to generate less complex versions of those meshes. For this purpose many methods have been proposed in the literature and it is of paramount importance that...

We compare selected mesh generation methods from intensity data and binary segmentions with respect to their application to surgical planning and make recommendations on how to receive smooth and accurate surface meshes for exemplary cases. We consider especially local curvature, distances between two meshes (before and after processing) and volume preservation as measures. Sample data from the...

In this paper we present a coder for polygon mesh connectivity that delivers the best connectivity compression rates meshes reported so far. Our coder is an extension of the vertex-based coder for triangle mesh connectivity by Touma and Gotsman [26]. We code polygonal connectivity as a sequence of face and vertex degrees and exploit the correlation between them for mutual predictive compression...

An automatic adaptive quadrilateral mesh conversion scheme for the generation of adaptive refinement meshes over analytical curved surfaces is proposed. The starting point of the quadrilateral mesh generator is a background triangular mesh of the curved surface. By a carefully controlled process to merge two triangles at a time the triangular mesh can be completely converted to quadrilaterals. ...

Wireless mesh network (WMN) research is an emerging field in network communications. However, WMNs pose several difficulties in the transmission of information, especially time critical applications such as streaming video and audio. In this paper, we provide an overview of several research papers which utilize mesh networks for streaming multimedia. We compare the results of the research and t...

Brain researchers, neurologists and neurosurgeons acquire 3D brain images from normal and diseased subjects with the idea to study the properties of brains, make comparisons and to measure changes caused by factors like age and disease. Over the last few years, significant efforts have been made [1, 2, 3, 4] to create software to extract the cerebral cortex (or other structures) from the brain,...

Image-based modeling of semi-transparent, dynamic phenomena is a challenging task. We present an optical tomography method that uses an adaptive grid for the reconstruction of a three-dimensional density function from its projections. The proposed method is applied to reconstruct thin smoke and flames volumetrically from synchronized multi-video recordings. Our adaptive reconstruction algorithm...

Parameterization of a 3D mesh is a fundamental problem in various applications of meshes. The approaches are widely used for parameterization because of its good properties, but they are almost based on triangle mesh. In this paper, we present a parameterization approach for the quadrilateral open mesh with complex topology. Since mesh simplification and weighted discrete mapping are adapted, t...
