Tracking with an Irregular Graph Pyramid

We propose to track objects with an irregular graph pyramid and find the correspondences for the objects only by the representative features in the top vertex of the pyramid. A state of the art tracking algorithm is used to associate the top vertex. Then, the information about the transformation is spread to the lower levels of the pyramid in a top down process by employing so-called correction vectors [60] (see publications). See Figure 2 for visualization.
