Motion Segmentation and Tracking by Embedding Global Model Within a Contextual Relaxation Scheme
IAPR Workshop on Machine Vision and Applications, pp. 455-458, 2000, Tokyo, Japan In this paper, we integrate the model-based tracking and local contexture (temporal and spatial) relaxation scheme into a MAP framework to track non-rigid objects such as human hands or faces. By combining them together, our algorithm is much more accurate and robust. The global shape model enables us to represent the dynamic and kinematic constraints. It also helps us to get a better initial segmentation and hence greatly reduce the computation of contextual relaxation. The local contextual constraints help us to get a more accurate support map by considering the local information. Hence it will reduce the significance of the error in the global model. Our algorithm can work autonomously and no need to initialize it. It can detect new moving objects and track them with new blobs. It can also keep track of a stalled object because we also utilize the spatial-temporal constraints. Some promising experimen...
