Hi all

The title and the abstract are as follows.

A Metric for Tracking Robustness in Real-Time Panorama Acquisition
Christopher Coffin , Sehwan Kim, Tobias Hollerer

ABSTRACT
To test the performance of tracking systems on a high level it is necessary
to perform both quantitative and qualitative analyses. This is
particularly true for concepts such as robustness that lack a clear-cut
quantitative definition. Addressing the difficulty inherent in collecting
user evaluation data, we present a metric which maps the quantitative
evaluation of systems to a close approximation of qualitative
robustness of the experience. This largely reduces the need to perform
qualitative analysis of tracking robustness. We motivate the
need for this metric through an analysis of four orientation tracking
systems used for the construction of environment maps. This initial
analysis demonstrates that ground truth error does not directly
reflect the results of a qualitative analysis. We then show that our
proposed metric is able to use the quantitative analysis of the systems
to correctly approximate the relative robustness of the systems
in our initial evaluation. Therefore our proposed metric is able to
estimate qualitative evaluation results, without the need for an additional
user study. Our metric requires only a set of representative
video sequences along with ground truth data for each frame in
terms of yaw, pitch, and roll.


Thanks.
