PROCEDE ET DISPOSITIF D'ESTIMATION DE MOUVEMENT DANS UNE SEQUENCE D'IMAGES ANIMEES

摘要

The method consists in estimating the motion by executing a gradient algorithm 2, 3 which minimises the square deviation between the local variations of luminance of the current point of the image and the point which is its counterpart in the previous image, in initialising 7 the execution of the algorithm with displacement values estimated in several directions inside the close causal neighbourhood of the current point and in propagating each estimate in the direction of scan of the lines of the image. Application: television.
