Tracking and segmenting people with occlusions by a sample consensus based method
One of the most difficult issues in visual tracking is to track people in groups, especially under occlusions. In this paper, we present a novel sample consensus based method, whi...

The tie-zone watershed: definition, algorithm and applications
In this work, a new type of watershed transform is introduced: the Tie-Zone WaterShed (TZWS). This region-based watershed transform does not depend on arbitrary implementation and...
