Abstract
The invention relates to a method of preprocessing a video image sequence consisting of a succession of interlaced frames for estimating motion between a first and a second frame, characterized in that a temporal filtering is performed on the basis of at least two input frames so as to deliver each of the two frames utilized by the motion estimator. The applications relate to motion estimators, in the field of video image compression or the conversion of television standards.
