Aiming at solving the coupling and time-consuming problem in motion estimation from images, a recursive estimator comprised of two sequential Kalman filters is proposed. 3D motion of a rigid object can be decomposed into translation of a point fixed on the object, called rotation center, and rotation w.r.t. this point. The rotational parameters are proved to be separate with the others, which means...
Tracking targets using mean shift algorithm is performed by iteratively translating a kernel in the image space such that the past and current target observations are similar. The standard mean shift, however, assumes that the initialization point falls within the basin of attraction of the desired mode. When tracking objects in FLIR imagery this assumption may not hold, particularly when the target's...
