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...
Segmentation of point clouds using smoothness constraint
Laser scanning Point cloud segmentation Reverse Engineering Industrial Reconstruction
2015/8/24
For automatic processing of point clouds their segmentation is one of the most important processes. The methods based on curvature and other higher level derivatives often lead to over segmentation, w...
Classification and segmentation of terrestrial laserscanner point clouds using local variance Information
3D laser scanning point cloud classifi cation segmentation
2015/8/24
With the use of terrestrial laser scanning, it is possible to capture thousands of 3-dimensional points on the surface of an object. The problem is that the vast quantity of data that needs to be mani...
Multi-scale texture and color segmentation of oblique airborne video data for damage classification
Earthquakes Damage Assessment Oblique
2015/8/21
Natural disasters are rapid and extreme events within the Earth's system. Since unheralded events are associated with widespread
destruction and high mortality, there is a need for rapid, accurate an...
A trained segmentation technique for optimization of object-oriented classification
