Abstract

Model-free tracking allows tracking of objects without prior knowledge of their characteristics. However, many algorithms require a manual initialization to select the target object(s) and perform only a coarse tracking. This article presents a new hybrid approach that allows combining a new fast, model-free tracking algorithm using 3D cameras with an arbitrary separate, slower tracking method that provides a time-delayed ground truth. In particular, we focus on human tracking human and employ Time-of-Flight cameras for the model-free tracking, based on ground truth provided by (multiple) Kinect cameras. The article describes the setup of the system, the model-free tracking algorithm and presents evaluation results for two different scenarios. Results show a high precision and recall, even with large time-delays of the ground truth of up to 10 s.
