Parallelizable global quasi-conformal parameterization of multiply-connected surfaces via partial welding
Zhipeng Zhu, Gary P. T. Choi, Lok Ming Lui
Conformal and quasi-conformal mappings have widespread applications in imaging science, computer vision and computer graphics, such as surface registration, segmentation, remeshing…
A unifying framework for -dimensional quasi-conformal mappings
Daoping Zhang, Gary P. T. Choi, Jianping Zhang +1
With the advancement of computer technology, there is a surge of interest in effective mapping methods for objects in higher-dimensional spaces. To establish a one-to-one correspon…
Topology-Preserving 3D Image Segmentation Based On Hyperelastic Regularization
Daoping Zhang, Lok Ming Lui
Image segmentation is to extract meaningful objects from a given image. For degraded images due to occlusions, obscurities or noises, the accuracy of the segmentation result can be…
Harmonic Beltrami Signature: A Novel 2D Shape Representation for Object Classification
Chenran Lin, Lok Ming Lui
There is a growing interest in shape analysis in recent years. We present a novel shape signature for 2D bounded simply-connected domains, named the Harmonic Beltrami signature (HB…
