Abstract (en)
[origin: WO2007099099A2] The invention relates to methods for determining a motion vector in a predetermined area of a sequence of digital images by comparing a current image to a preceding image. The current image and the preceding image are prepared by the same filter for image adaptation. Distance vectors between a pixel of a current image and balanced pixels of the preceding image in a predetermined environment are determined, said distance vectors being averaged in order to form a displacement vector for the pixel. The displacement vectors are averaged and the displacement vector is produced.
