VIDEO ENCODING AND DECODING BY INHERITANCE OF A FIELD OF MOTION VECTORS

摘要

A method is provided for coding a current image. The method includes determining, in a first image, different from the current image, a group of k′ pixels corresponding to a current group of k pixels (k′≦k) to be coded of the current image; calculating a motion vector between each of the k′ pixels of the first image and a corresponding pixel of a second image different from the current image, on completion of which a field of k′ motion vectors is obtained; and predicting the pixels or of the motion of the current group of k pixels of the current image on the basis of the field of k′ motion vectors which is obtained.

1. A method for coding a current image comprising the following acts:
determining by a coding device, in a first image different from the current image, a group of k′ pixels corresponding to a current group of k pixels (k′≦k) to be coded of the current image; calculating by the coding device a motion vector between each of the k′ pixels of the first image and a corresponding pixel of a second image different from the current image, on completion of which a field of k′ motion vectors is obtained, and predicting with the coding device the pixels or the motion of the current group of k pixels of said current image on the basis of the field of k′ motion vectors which is obtained.
