Cloud Sphere: A 3D Shape Representation via Progressive Deformation
Zongji Wang, Yunfei Liu, Feng Lu
In the area of 3D shape analysis, the geometric properties of a shape have long been studied. Instead of directly extracting representative features using expert-designed descripto…
A New Way to Factorize Linear Cameras
Feng Lu, Ziqiang Chen
The implementation details of factorizing the 3x4 projection matrices of linear cameras into their left matrix factors and the 4x4 homogeneous central(also parallel for infinite ce…
Newton-Type Iterative Solver for Multiple View Triangulation
F. Lu, Z. Chen
In this note, we show that the L2 optimal solutions to most real multiple view L2 triangulation problems can be efficiently obtained by two-stage Newton-like iterative methods, whi…
A General Homogeneous Matrix Formulation to 3D Rotation Geometric Transformations
Feng Lu, Ziqiang Chen
We present algebraic projective geometry definitions of 3D rotations so as to bridge a small gap between the applications and the definitions of 3D rotations in homogeneous matrix…
A Unified Framework of Elementary Geometric Transformation Representation
F. Lu, Z. Chen
As an extension of projective homology, stereohomology is proposed via an extension of Desargues theorem and the extended Desargues configuration. Geometric transformations such as…
