Surface Construction Based on Quadrilateral Mesh
Found in: Information and Computing Science, International Conference on
By Wei Li, Zhuoqi Wu, Ichiro Hagiwara, Yong Jiang
Issue Date:April 2011
pp. 77-79
In this paper, a method of constructing smooth surface based on quadrilateral mesh by using C-curves is presented. Instead of using the conventional basis {t3, t2, t, 1}, C-curves are developed by using the basis {sint, cost, t, 1}. Compared with the tradi...
 
Investigation into registration of scanned 3D image based on geometric feature identification
Found in: International Conference on Computer Supported Cooperative Work in Design
By Lirong Wang, Fang Xu, Ichiro Hagiwara
Issue Date:April 2009
pp. 648-653
This paper investigates geometric feature extraction from scanned image and applies it in multi-view image registration. The presented registration approach includes three steps, feature extraction, coarse registration and fine registration. Firstly, featu...
 
An Efficient Registration Algorithm of Multi-view Three-Dimensional Images
Found in: Computer Science and Information Engineering, World Congress on
By Lirong Wang, Fang Xu, Ichiro Hagiwara
Issue Date:April 2009
pp. 703-706
This paper proposes a kind of feature extraction based efficient registration algorithm including coarse and fine registrations. During coarse registration, feature points are detected, and feature point links are set up according to the relationship estab...
 
Design and Implement of File Linked Distributed File System
Found in: Computer Science and Information Engineering, World Congress on
By Hao Peng, Li-Rong Wang, Jiacai Wang, Ichiro Hagiwara
Issue Date:April 2009
pp. 305-309
In normal distributed file system, the concurrency of same file's copies was paid many attentions. Actually the relationship between different files also affects the operation to the other files, especially in a serialized file group occurred in Computer S...
 
A Topology Preserved Mesh Simplification Algorithm
Found in: Computer Science and Information Engineering, World Congress on
By Lirong Wang, Jinzhu Li, Ichiro Hagiwara
Issue Date:April 2009
pp. 698-702
These large-volume mesh models face challenge in rendering, storing, and transmission for the further geometrical reconstruction. This paper presents a feature extraction based mesh simplification method to get a topology preserved simple mesh model. Seque...
 
A Method of Generating Smooth Surface Using C-curves
Found in: Computer Aided Design and Computer Graphics, International Conference on
By Wei Li, Zhuoqi Wu, Ichiro Hagiwara
Issue Date:December 2005
pp. 67-72
A method of constructing piecewise G^1 continuous spline surface using boundary C-curves is presented. C-curves are developed by the basis {sin t, cos t, t, 1}, and it overcomes some shortcomings of the nonuniform rational B-splines (NURBS) model. How to d...
