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.

摘要： A method for decoding a coded data stream representing a video having a first view and a second view different from the first view, in which a reference image of the second view is previously reconstructed. For a current block of a current image of the first view, a motion information item associated with the current block representative of a displacement of the current block in the previously reconstructed reference image, is obtained. A prediction block is obtained based on the previously reconstructed reference image of the second view and of the obtained motion information item. The current block is reconstructed based on the prediction block, a prediction residual information item decoded based on the coded data stream and a difference information item calculated between a first block associated with the first view and a second block associated with the second view and decoded based on the coded data stream.
