Abstract :
Visual cues are often very difficult to track. We use an effective least squares estimation of the Lie algebra parameters to find the affine transformation involved in a visual region tracking. These parameters represent the geodesis of the optimal transformation orbit. Our experiments validate the effectiveness of the method.
