Coverage Quality in Visual Sensor Networks

Improving Energy-Efficient Target Coverage in Visual Sensor Networks

Target coverage is one of the important problems in visual sensor networks. The coverage should be accompanied with an efficient use of energy in order to increase the network lifetime. In this paper, we address the maximum lifetime for visual sensor networks (MLV) problem by maximizing the network lifetime while covering all the targets. For this purpose, we develop a simulated annealing (SA) ...

Mesh Simplification Based on Shading Characteristic

Mesh simplification is a key research area in scientific visualization and virtual reality. The paper presents a new method of polyhedral model simplification based on vision characteristic and edge collapse. This method determines model’s vision characteristic by computing the maximum product of angle between normal of vertex and adjacent triangles with area of these triangles. It can achieve ...

Mesh Surface Simplification Based on Constrained Energy

A triangle-mesh-surface-simplification algorithm based on a constrained energy function is proposed. In the algorithm, vertices are deleted iteratively according to the dimension-less energy function, which represents the cost of surface modification by vertex deletion and subsequent hole re-triangulation. The energy function is used both for selecting a vertex with the minimum energy for delet...
