GraphReg: Dynamical Point Cloud Registration with Geometry-aware Graph Signal Processing
Zhao Mingyang, Ma Lei, Jia Xiaohong +2
This study presents a high-accuracy, efficient, and physically induced method for 3D point cloud registration, which is the core of many important 3D vision problems. In contrast t…
Robust Ellipsoid-specific Fitting via Expectation Maximization
Zhao Mingyang, Jia Xiaohong, Ma Lei +3
Ellipsoid fitting is of general interest in machine vision, such as object detection and shape approximation. Most existing approaches rely on the least-squares fitting of quadrics…
LARNet: Lie Algebra Residual Network for Face Recognition
Xiaolong Yang, Xiaohong Jia, Dihong Gong +3
Face recognition is an important yet challenging problem in computer vision. A major challenge in practical face recognition applications lies in significant variations between pro…
Adaptive Morphological Reconstruction for Seeded Image Segmentation
Tao Lei, Xiaohong Jia, Tongliang Liu +3
Morphological reconstruction (MR) is often employed by seeded image segmentation algorithms such as watershed transform and power watershed as it is able to filter seeds (regional…
Continuous Collision Detection for Composite Quadric Models
Yi-King Choi, Wenping Wang, Bernard Mourrain +3
A composite quadric model (CQM) is an object modeled by piecewise linear or quadric patches. We study the continuous detection problem of a special type of CQM objects which are co…
Homeomorphic approximation of the intersection curve of two rational surfaces
Liyong shen, Jin-san Cheng, Xiaohong Jia
We present an approach of computing the intersection curve of two rational parametric surface and , one being projectable and hence can easily be…
Using Smith Normal Forms and mu-Bases to Compute all the Singularities of Rational Planar Curves
Xiaohong Jia, Ron Goldman
We prove the conjecture of Chen, Wang and Liu in [8] concerning how to calculate the parameter values corresponding to all the singu- larities, including the infinitely near singul…
