About this paper
Tobias Böttger, Markus Ulrich, Carsten Steger
Researchers at MVTec Software GmbH developed a real-time tracking scheme for rigid objects, achieving subpixel-precise estimation of position, scale, and rotation. The CPU-efficient method, operating around 80 frames per second, demonstrates robustness against occlusions and illumination variations, including recovery from complete object disappearance.
Key insights
- Utilizing normalized direction vectors for similarity calculation provides intrinsic robustness to illumination changes and background clutter.
- A reliable self-diagnosis mechanism with progressive search space expansion enables recovery after complete object occlusion.
- A regularized model update mechanism allows adaptation to minor object deformations, extending applicability beyond strictly rigid objects.
