Automatic acquisition and tracking of mobile target in image sequences
The targeted users and customers are the multimedia industry actors, and all academic or industrial laboratories interested in object tracking in videos.
AACI is structured in 4 steps. First of all, dominant motion estimation is performed using Motion2D software. Then each pixel of current frame is labeled either as “conform to dominant motion” or “non-conform to dominant motion” by minimum-cut/maximumflow minimization of a cost function, described in [1].
Then each detection is added to a Trellis, and is validated if it is persistent in size and position for a short period of time (the Trellis depth) or discarded otherwise. Finally, each validated detection is tracked using Mean-shift algorithm, as explain in [2].
