Automatically Assessing Limb Alignment and Hip Fracture Using 3D Models
Found in: Computing in Science & Engineering
By Qi Xing,Rui Han,Yanlin Li,Wenzhen Yang,Jim X. Chen
Issue Date:March 2013
pp. 10-20
To allow an efficient assessment of lower limb alignment and hip fracture, 3D lower limb bone models are reconstructed from patient-specific computed tomography images. The 3D feature-construction system shown here automatically extracts 3D features (cente...
 
3D Automatic Feature Construction System for Lower Limb Alignment
Found in: Cyberworlds, International Conference on
By Qi Xing, Wenzhen Yang, Mark M. Theiss, Jihui Li, Qiang Peng, Jim X. Chen
Issue Date:October 2010
pp. 375-382
Accurate measurement of lower limb alignment is vital for orthopedic surgery planning. Based on the 3D lower limb bone models reconstructed from CT images, a 3D feature construction system is developed to find the lower limb alignment. This paper presents ...
 
An Efficient Visualization of Implicit Surfaces
Found in: Computer Science and Software Engineering, International Conference on
By Jun Yang, Qi Xing, Changqian Zhu
Issue Date:December 2008
pp. 369-372
In this paper, we present a novel rendering algorithm for implicit surfaces by using a particle system. First, an alternative initial technique based on bundles of parallel lines is used to find initial points that are evenly distributed on the surface. Be...
 
Structure-aware shape processing
Found in: SIGGRAPH Asia 2013 Courses (SA '13)
By Daniel Cohen-Or, Hao (Richard) Zhang, Qi-Xing Huang, Michael Wand, Niloy Mitra, Vladimir Kim
Issue Date:November 2013
pp. 1-20
Shape structure is about the arrangement and relations between shape parts. Structure-aware shape processing goes beyond local geometry and low level processing, and analyzes and processes shapes at a high level. It focuses more on the global inter and int...
     
Fine-grained semi-supervised labeling of large shape collections
Found in: ACM Transactions on Graphics (TOG)
By Hao Su, Qi-Xing Huang, Leonidas Guibas
Issue Date:November 2013
pp. 1-10
In this paper we consider the problem of classifying shapes within a given category (e.g., chairs) into finer-grained classes (e.g., chairs with arms, rocking chairs, swivel chairs). We introduce a multi-label (i.e., shapes can belong to multiple classes) ...
     
An optimization approach for extracting and encoding consistent maps in a shape collection
Found in: ACM Transactions on Graphics (TOG)
By Adrian Butscher, Guo-Xin Zhang, Leonidas Guibas, Lin Gao, Qi-Xing Huang, Shi-Min Hu
Issue Date:November 2012
pp. 1-11
We introduce a novel approach for computing high quality point-to-point maps among a collection of related shapes. The proposed approach takes as input a sparse set of imperfect initial maps between pairs of shapes and builds a compact data structure which...
     
Digital anastylosis of the Octagon in Ephesos
Found in: Journal on Computing and Cultural Heritage (JOCCH)
By Barbara Thuswaldner, Hilke Thur, Michael Hofer, Qi-Xing Huang, Robert Kalasek, Simon Flory
Issue Date:July 2009
pp. 1-27
Anastylosis is the archaeological and architectural reconstruction of a ruined monument at the historic site after careful study of the remaining original elements. We present research results concerning 3D technologies that are used in the digital anastyl...
     
Reassembling ancient monuments via constrained registration
Found in: ACM SIGGRAPH 2007 posters on XX (SIGGRAPH '07)
By Barbara Thuswaldner, Michael Hofer, Qi-Xing Huang, Simon Flory
Issue Date:August 2007
pp. 135-es
As demonstrated in our work [Huang et al. 2006] fracture surfaces of broken solids contain rich geometric information that are sufficient for reassembly based on geometric matching. However, the task of reassembling an ancient monument from its building bl...
     
Reassembling fractured objects by geometric matching: Copyright restrictions prevent ACM from providing the full text for this work.
Found in: ACM SIGGRAPH 2006 Papers (SIGGRAPH '06)
By Helmut Pottmann, Michael Hofer, Natasha Gelfand, Qi-Xing Huang, Simon Flory
Issue Date:July 2006
pp. 11-es
We present a system for automatic reassembly of broken 3D solids. Given as input 3D digital models of the broken fragments, we analyze the geometry of the fracture surfaces to find a globally consistent reconstruction of the original object. Our reconstruc...
