PROCEDE ET DISPOSITIF DE RESTAURATION D'UNE SEQUENCE VIDEO

摘要

In order to restore a video sequence consisting of a plurality of images each comprising at least one block of pixels: the value of the similarity between a block of pixels to be restored in the current image and a plurality of blocks of a reference image is calculated (10); the block of the reference image for which the value of the similarity is an extremum is determined; a similarity map is constructed (12) around the extremum; the similarity map is modeled (14) so as to obtain a model defined by a predetermined number of parameters; a local restoration filter is constructed (16) from the parameters of the model; and the pixels of the block to be restored are filtered (18) by applying to them the local restoration filter.
