Parallelizable inpainting and refinement of diffeomorphisms using Beltrami holomorphic flow
Found in: Computer Vision, IEEE International Conference on
By Tsz Wai Wong,Xianfeng Gu,Tony F. Chan,Lok Ming Lui
Issue Date:November 2011
pp. 2383-2390
In this paper, we propose novel algorithms for inpainting and refinement of diffeomorphisms. We first represent a diffeomorphism by its Beltrami coefficient. Then it is possible to refine and inpaint the diffeomorphism by processing this Beltrami coefficie...
Compression of surface registrations using Beltrami coefficients
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Lok Ming Lui, Tsz Wai Wong, Paul Thompson, Tony Chan, Xianfeng Gu, Shing-Tung Yau
Issue Date:June 2010
pp. 2839-2846
Surface registration is widely used in machine vision and medical imaging, where 1-1 correspondences between surfaces are computed to study their variations. Surface maps are usually stored as the 3D coordinates each vertex is mapped to, which often requir...

Automatic Landmark Tracking and its Application to the Optimization of Brain Conformal Mapping
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Lok Ming Lui, Yalin Wang, Tony F. Chan, Paul M. Thompson
Issue Date:June 2006
pp. 1784-1792
Anatomical features on cortical surfaces are usually represented by landmark curves, called sulci/gyri curves. These landmark curves are important information for neuroscientists to study brain diseases and to match different cortical surfaces. Manual labe...
Shape Analysis of Planar Multiply-Connected Objects Using Conformal Welding
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Lok Ming Lui,Wei Zeng,Shing-Tung Yau,Xianfeng Gu
Issue Date:July 2014
pp. 1-1
Shape analysis is a central problem in the field of computer vision. In 2D shape analysis, classification and recognition of objects from their observed silhouettes are extremely crucial but difficult. It usually involves an efficient representation of 2D ...
