Abstract
Optical flow is measured between a first image and a second image by evaluating a match quantifying parameter in respect of a set of candidate flow vectors. The set of candidate flow vectors includes one or more flow vectors selected in dependence upon one or more neighbor flow vectors associated with one or more neighboring pixels to the given pixel which have previously calculated respective match quantifying parameters indicative of closest matches for the one or more neighboring pixels. The set of candidate flow vectors also includes adjacent flow vectors corresponding to target pixels surrounding the target pixels identified by the neighbor flow vectors. One or more randomly selected random flow vectors is also added to the set of candidate flow vectors. The calculated match quantifying parameters are weighted in dependence upon whether the corresponding candidate flow vector is similar to any other candidate flow vector.
