ABSTRACT:
A method and apparatus for tracking moving objects, such as people, in real time by grouping existing feature paths from a current video frame with preexisting clusters from current video frames. Grouping is accomplished by selecting, as a candidate cluster to a specified feature path, the cluster having the closest relative distance to the specified feature path. The relative distance is calculated according to a function having a first component and a second component. The first component is representative of a maximum displacement between the select feature path and the candidate cluster, and the second component is representative of the difference between velocity vectors defining the select feature path motion and velocity vectors defining the candidate cluster motion. The method and apparatus also provide for updating the candidate cluster with parameters obtained from the select feature path and for merging overlapping clusters.
