Generic object tracking for fast video annotation

This article describes a method for fast video annotation using an object tracking technique. This work is part of the development of a system for interactive television, where video objects have to be identified in the video program. This environment puts specific requirements on the object tracking technique. We propose to use a generic technique based on keypoints. We describe three contributions in order to best satisfy those requirements: a model for a broader temporal use of the keypoints, an ambient color adaptation pre-treatment enhancing the keypoint detector performance, and a motion based bounding box repositioning algorithm. Finally, we present experimental results to validate those contributions
