Patent ID: 8306123

Claim:
A method for motion estimation of a first image frame and a second image frame, comprising: estimating a motion vector correlating a portion of pixels of the first and second image frame, the first and second image frame being part of an image frame sequence, wherein: the motion vector is obtained by a predominant motion detection generating a global motion vector based on a previously determined motion vector, the previously determined motion vector correlating a portion of pixels of earlier image frames of the image frame sequence; the estimating the motion vector is performed on the basis of the global motion vector; and the predominant motion detection comprises: forming a histogram on the basis of the motion vector, filtering the motion vector, from among a plurality of motion vectors, on the basis of the histogram, the filtering comprising: sorting the motion vectors; selecting, in a binarization, the motion vector from the sorted motion vectors; and substituting the motion vector, which is selected in the binarization, with a non-selected motion vector of the sorted motion vectors or a predetermined motion vector; and distributing the motion vector, which is substituted as a result of the filtering, over at least a portion of the second image frame.
