摘要： A decoding method including: decoding at a current time instant a current image having at least two views respectively representative of a same scene. The decoding includes: deriving a disparity motion vector for a current block; predictively decoding the current block according to the derived disparity motion vector; and during the deriving: constructing a plurality of lists of disparity motion vectors, including at least one list in which at least two disparity motion vectors have been derived respectively according to at least two different estimation methods; applying a first function to the at least two disparity motion vectors of the at least one list, to obtain one disparity motion vector for each of the at least one list, and applying a second function to the disparity motion vectors of the plurality of lists to deliver the derived disparity motion vector.

摘要： A method and a device for decoding a data stream representative of a multi-view video. Syntax elements are obtained from at least one part of the stream data, and used to reconstruct at least one image of a view of the video. Then, at least one item of metadata in a predetermined form is obtained from at least one obtained syntax element, and provided to an image processing module. Also provided are a method and a device for processing images configured to read said at least one item of metadata in the predetermined form and use it to generate at least one image of a virtual view from a reconstructed view of the multi-view video.

摘要： A method for decoding a data stream representative of an image sequence. At least one current block of a current image in the image sequence is encoded using a predictor block of a reference image, the predictor block being identified in the reference image via location information. An information item enabling the reference image to be identified from a set of reference images is obtained. When the reference image satisfies a predetermined criterion, the location information of the predictor block is decoded using a first decoding mode, otherwise the location information of the predictor block is decoded using a second decoding mode, the first and second decoding modes including at least a different decoding parameter. The current block is then reconstructed from the predictor block.

摘要： A method and apparatus for decoding a current view belonging to a previously coded multi-view image. The method includes: determining, in a set of views belonging to the multi-view image or to another multi-view image, a pathway of views that are necessary for the decoding of the current view, the pathway comprising at least one as yet undecoded view; decoding the at least one view not yet decoded; and decoding the current view on the basis of a set of coded data representative of at least one difference between the current view and another view of the multi-view image or of another multi-view image, and of the at least one decoded view.

摘要： A method is provided for encoding at least one current image. The method implements, at an image capturing terminal, for at least one portion to be encoded of the current image: determining a piece of information related to manipulation of the terminal by a user, in relation with the at least one captured current image; obtaining at least one piece of data related to the current image by transforming the determined piece of information; and from the obtained piece of data, implementing at least one of the following acts: predicting a piece of movement information associated with the at least one portion of the current image, and determining at least one characteristic of an encoding mode associated with the at least one portion of the current image.

摘要： A method is provided for decoding a current image having at least two views which are respectively representative of a same scene. The decoding method includes derivation of a disparity motion vector and, during the derivation: constructing at least one list of disparity motion vectors, in which at least two disparity motion vectors have been obtained respectively according to two different estimation methods; and applying a function to the at least two disparity motion vectors of the list. The method is applicable, for example, to a current image Ik of an MVV or MVD type.

摘要： A method and device for encoding an image divided into blocks. The image contains two separate zones. The method implements the following: only in the event where the current block pertains to one of the zones of the image: encoding the current block using a prediction, the current block being predicted using a previously encoded and then decoded block located in the other zone of the image, the blocks of the other zone having been previously encoded and then decoded, and encoding information indicating the application of the prediction; and for any decoded block pertaining to the other zone of the image, storing the decoded block data.

摘要： A process for coding an image of a view from among a plurality of views, including the following steps: selecting a first or a second coding method to code image data from the image; generating a data signal containing information indicating whether it is the first or the second coding method that has been selected, and, if it is the first coding method, coding the original image data so as to provide coded original data, and, if it is the second coding method, coding processed image data from the image obtained by image processing of the original image data so as to provide coded processed data; and coding information describing the image processing which has been applied.
