Laser Scanning, Theory and Applications
The pair-wise registrations generate a graph, in which the nodes are the individual scans and the edges are the transformations between the scans. ...
However, when those conditions cannot be guaranteed, the point-to-plane ICP is prone to fail (Gelfand et al.,2003) . ...
For generalization the conjugate overlapping regions of the scene in the left and right surface can be represented as (,,) f xyz and (,,) gxyz no matter the representation of the surface is point cloud ...

A non-device-specific approach to display characterization based on linear, nonlinear, and hybrid search algorithms
2013
Journal of Vision
The standard display characterization called "gamma correction" and the following linear color transformation procedure are established for CRT displays and widely used in the current vision science field ...
However, the standard twostep procedure is based on the internal model of CRT display devices, and there is no guarantee as to whether the method is applicable to the other types of display devices such ...

On enriching the Levin–Wen model with symmetry
2015
Journal of Physics A: Mathematical and Theoretical
The input data for the Levin-Wen model is a unitary fusion category, but the same model also works for unitary multi-fusion categories. ...
In this paper, we provide the details for this extension of the Levin-Wen model, and show that the extended Levin-Wen model is a natural playground for the theoretical study of symmetry protected and symmetry ...

Then the tetrahedron gxyz is inside K(g) which means the centers of the other objects must lie outside gxyz. This implies K(g) is the closest object to g. ...
Because K is convex, this implies that the triangle xyz is inside the object K. ...
The KDS then performs an event-driven simulation of the motion of the objects, updating the structure whenever an event happens, that is, when a certificate fails. ...
