VERFAHREN UND EINRICHTUNG ZUR BEWEGUNGSABSCHAETZUNG IN EINER SICH BEWEGENDEN BILDFOLGE.

摘要

The method consists in estimating motion by performing a gradient algorithm which minimalizes the mean square deviation of local luminance variations of the present pel of the picture with the pel that is homologous with it in the prior picture, in initializing the execution of the algorithm by displacement values estimated along several directions within the close causal neighborhood of the present pel and in propagating each estimate in the scanning direction if the picture lines.
