摘要： A method of tracking a target object in frames of video data includes receiving a first tracking position associated with the target object in a first frame of a video sequence; identifying, for a second frame of the video sequence, a plurality of representation levels and at least one node for each representation level; determining, by a processor, a second tracking position in the second frame by estimating motion of the target object in the second frame between the first frame and the second frame; determining, at each representation level by the processor, a value for each node based on a conditional property of the node in the second frame; and adjusting, by the processor, the second tracking position based on the values determined for each of the nodes and interactions between at least some of the nodes at different representation levels.

摘要： An object tracking device includes a short-term processing portion and a long short-term processing portion that are implemented by circuitry and work in a collaborative manner to track an object. The short-term processing portion includes a filter that tracks the object based on short-term memory and spatiotemporal consistency. The long short-term processing portion performs key-point matching-tracking and estimation based on a key-point database in order to track the object. A controller determines an output of the object tracking device based on the processing conducted by the short-term and long short-term processing portions of the tracking device, respectively.
