Abstract: The present invention relates to a video tracker which allows automatic tracking of a selected area over video frames. Motion of the selected area is defined by a parametric motion model. In addition to simple displacement of the area it can also detect motions such as rotation, scaling and shear depending on the motion model. The invention realizes the tracking of the selected area by estimating the parameters of this motion model in the complex discrete wavelet domain. The invention can achieve the result in a non-iterative direct way. Estimation carried out in the complex discrete wavelet domain provides a robust tracking opportunity without being effected by noise and illumination changes in the video as opposed to the intensity-based methods. The invention can easily be adapted to many fields in addition to video tracking.
