POOR TEXTURAL IMAGE MATCHING BASED ON GRAPH THEORY
Poor Textural Image Image Matching Graph Matching Affinity Tensor Power Iteration Algorithm
2016/7/28
Image matching lies at the heart of photogrammetry and computer vision. For poor textural images, the matching result is affected by low contrast, repetitive patterns, discontinuity or occlusion, few ...
Skeletonization and segmentation of point clouds using octrees and graph theory
terrestrial laser data, data processing, skeletonization skeleton extraction graph theory graph replacement graph collapsing octree terrestrial laser scanning
2015/8/25
In this part of literature we will present a new way of extracting a skeleton out of a point cloud. Our approach is based on looking at the attributes of data points in small parts of the space. The s...

基于双重编码遗传算法和图论的自压树状管网优化（Optimization of Gravity Tree-type Pipe Network Based on Dual Coding Genetic Algorithm and Graph Theory）
树状管网 优化 遗传算法
2010/1/28
以投资最小为目标函数，压力、流速、管径等限制为约束条件，建立了自压树状管网优化数学模型，并采用改进遗传算法进行求解。根据树状管网优化的特点，遗传算法采用二进制编码和整数编码相结合的双重编码，实现了同时对管网布置形式和管径进行优化。根据图论中树的性质，在产生初始解及变异操作时，采用基于圈的方法，对交叉方法进行了改进，从而减少了不可行解的产生。同时对遗传算法的操作过程进行了改进，结合了模拟退火算法，调...
