Object Trackers: Approaches and Applications

Object tracking is a powerful algorithm component and one of the fundamental building blocks for many real-world computer vision applications. Object trackers provide two main benefits when incorporated into a localization module. First, trackers can reduce overall computation and power requirements by allowing a reduction in the frequency at which detections must be generated. Second, trackers can maintain the identity of an object across multiple frames, which is important for many applications. Recent advances in deep learning provide us with a unified method for designing detectors, but we still have many design choices for trackers. In this talk we will describe three basic tracker approaches and their use in video analytics applications including face recognition, people counting and action recognition. We will also provide insights on how recent advances in recurrent neural networks and reinforcement learning can be used for enhancing trackers.
