Abstract:

Many applications in media production need information about moving objects in the scene, e.g. insertion of computer-generated objects, association of sound sources to these objects or visualisation of object trajectories in broadcasting. We present a GPU accelerated approach for detecting and tracking salient features in image sequences. The obtained feature point trajectories are then clustered to obtain a motion segmentation of the set of feature trajectories. We present evaluation results and discuss the application of the proposed approach for associating audio sources to objects to support audio rendering for virtual sets.
