Abstract
A method to enhance motion estimation is provided. The method includes providing a motion estimator, obtaining at least two candidate motion vectors from the motion estimator and applying an error function having a penalty that depends on the position and size of the candidate motion vectors. A device for recursive motion vector estimation having enhanced convergence is also provided. The device includes a vector generator and a best vector selector. The best vector selector comprises means to evaluate candidate motion vectors by applying an error function having at least a penalty that depends on the position and size of the candidate motion vectors.
Claims4
A method to enhance motion estimation, said method comprising:
- providing a motion estimator;
- obtaining at least two candidate motion vectors from said motion estimator;
- and
- applying an error function having a penalty that depends on the position and size of said candidate motion vectors.
A device for recursive motion vector estimation having enhanced convergence which comprises:
- a vector generator for generating a plurality of candidate motion vectors associated with selected regions in at least a first and a second video image;
- a best vector selector for comparing said candidate motion vectors of selected regions in a first and a second video image, said best vector selector comprising means for evaluating said candidate motion vectors by applying an error function having at least a penalty that depends on the position and size of said candidate motion vectors.
