Evaluation. The evaluation aims at comparing our approach against the particle filter based
approaches [5][18][9] and online learning based approach [20] in estimating the translation (in x, y,
and z axis) and rotation (roll, pitch and yaw) parameters. We compute the root mean square (RMS)
errors (translation, rotation) and average time per frame. Table I shows our approach outperforms
[5] and [18] over all sequences. Unlike [5] our approach only uses depth data for 3D tracking. It
also performs better than [9] on average of about 0.31 mm and 1.16 deg in estimating the
translation and rotation parameters respectively. Our approach requires much less computational
time (1.7 ms per frame) when compared with [9] (131 ms). Though our approach performs on par
with [20] in terms of run-time, it performs better in estimating the translation (by 0.31 mm) and
rotation parameters (by 0.15 deg) on average.

6. Conclusion
We have presented a framework for combining object tracking and object localization to provide
robust tracking performance in a challenging scenario. A quantitative analysis of the evaluation on
popular test data set is also presented. The evaluation shows that our approach performs better than
the state of art in terms of estimating the translation and rotation parameters. The approach is
