Abstract

At least one method of, and at least one apparatus, system and computer readable medium for, matching moving targets between two camera views are discussed herein. The moving targets are tracked over video frames in each of the camera views and motion directions of the targets are recorded. Appearance similarities for cross-camera target pairs over synchronized ones of the video frames are determined. A joint probability model of co-occurred ones of the recorded motion directions for the camera views are determined using a weighted accumulation of the recorded motion directions of the cross-camera target pairs, where accumulation weights used in determining the joint probability model are derived from the determined appearance similarities. The moving targets between the camera views are matched using the joint probability model.
