Claim Text:
1. A method of tracking a target object in frames of video data, comprising: 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, wherein the plurality of representation levels includes a bounding box level; determining, by a processor, at least one node for each representation level, wherein the at least one node for the bounding box level is included in a second tracking position associated with the target object in the second frame determined by estimating motion of the target object between the first frame and the second frame; determining, at each of the plurality of representation levels by the processor, a value for each node based on a conditional property of the node; and adjusting, by the processor, the second tracking position based on the values determined for each of the nodes and interactions between at least the at least one node for the bounding box level and the at least one node for a different representation level.
