Robust Software for Computing Camera Motion Parameters

Tags:
data visualization

Overview This paper revisits the method of Tsai, Huang, and Zhu for the computation of camera motion parameters in computer vision. It elucidates some spectral properties of the homography matrices that arise, which are rank-one perturbations of rotation matrices. The paper shows how to correct for noise by finding the rank-one perturbation of a rotation closest to a give matrix. The paper illustrates some of the inaccuracies and computational failures that can arise when using the formulas given by Tsai, and it proposes new formulas that avoid these pitfalls. A computational experiment shows that the new methods are indeed quite robust.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
