CC-Modeler: A topology generator for 3-D city models
3-D City models topology generator building reconstruction visualization
2016/5/20
In this paper, we introduce a semi-automated topology generator for 3-D objects, CC-Modeler (CyberCity Modeler).Given the data as point clouds measured on Analytical Plotters or Digital Stations, we p...
Likelihood-based classification of high resolution images to generate the initial topology and geometry of land cover segments
Likelihood-based classification Maximum likelihood classification Geo-information systems
2016/5/20
This paper’s origin is to reach for a way for automatic initiation of shape hypothesis for Model Based Image Analysis (MBIA) in the specific case of agricultural fields. A solution is to start with lo...
Measurements of Forest Inventory Parameters on Terrestrial Laser Scanning Data Using Digital Geometry and Topology
digital geometry digital topology image processing skeletonization
2015/12/8
This paper gives some mathematical methods for the automatic analysis and determination of forest management parameters in particular for the measurements of geometrical sizes on terrestrial scanning ...
Topology-Preserving Network Snakes
Computer Vision Active Contour Models Optimization Segmentation Networks Topology Roads
2015/12/4
Active contour models have been part of extensive research since their introduction in the late eighties, because their concept of coupling the image data with shape control is a powerful method to de...
3D Spatial Operations for Geo-DBMS - Geometry VS. Topology
Spatial Database Geometry Query Three-dimensional GIS
2015/12/2
Geo-DBMS becomes very important medium for GIS as it can handle and manage (e.g. retrieve and update) large volume of spatial data. Providing 3D spatial database with appropriate operation tools such ...
This paper reviews 3D topology within Land Administration Domain Model (LADM) international standard. It is important to review characteristic of the different 3D topological models and to choose the ...
The Basic Topology Issues on Spherical Surface Quaternary Triangular Mesh
SGDM Manifold SQTM Spherical Surface Digital Topology Spherical Surface Topology Paradox
2015/10/9
SGDM (Sphere Grid Data Model) is an efficient method to deal with the global data because of the advantages of multi-resolution
and hierarchy. However, SGDM has no distinct descriptions and lack of ...
AUTOMATIC EXTRACTION AND TOPOLOGY RECONSTRUCTION OF URBAN VIADUCTS FROM LIDAR DATA
Airborne LiDAR Point Cloud Overpass Urban Viaducts Recognition Topology Reconstruction
2015/9/21
Urban viaducts are important infrastructures for the transportation system of a city. In this paper, an original method is proposed to automatically extract urban viaducts and reconstruct topology of ...
Optimal Wire and Transistor Sizing for Circuits with Non-Tree Topology
Optimal Wire Transistor Sizing Circuits Non-Tree Topology
2015/8/14
Conventional methods for optimal sizing of wires and transistors use linear RC circuit models and the Elmore delay as a measure of signal delay. If the RC circuit has a tree topology the sizing proble...
AN INTEGRATED MODEL FOR FUZZY TOPOLOGY AND QUALITATIVE DISTANCE FOR DISCRETE SPACE
topologic relation model discrete space fuzzy region
2015/8/10
The topological relationship of disjoint is ubiquitous in physical world, while the traditional topological relationship models do not take more considerations about it. Point set topology is exhausti...

Adjoint Formulations Topology,Shape Discrete Optimization
2015/7/2
The use of adjoints for PDE constrained optimization problems has become a common design tool in many areas of applied engineering. The use of adjoint methods for shape optimization has received much ...
Traditional polygon-arc-node topological relationships (TRs) is standard in vector GIS. That has been explicitly represented by many commercial GIS systems. In the case of Intelligent Transportation S...
