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…
Inconsistent Surface Registration via Optimization of Mapping Distortions
Di Qiu, Lok-Ming Lui
We address the problem of registering two surfaces, of which a natural bijection between them does not exist. More precisely, only a partial subset of the source surface is assumed…
Parallelizable global conformal parameterization of simply-connected surfaces via partial welding
Gary P. T. Choi, Yusan Leung-Liu, Xianfeng Gu +1
Conformal surface parameterization is useful in graphics, imaging and visualization, with applications to texture mapping, atlas construction, registration, remeshing and so on. Wi…
