摘要： A method of determining a partition into distinct regions of a set of coefficients representative of at least a part of an image in order to insert a watermark comprises the following steps: generation (E501) of a centred pseudo-random sequence (w) equal in size to the cardinal number (N) of the said set of coefficients, formed from centred pseudo-random sub-sequences; modulation (E502) of the said set of coefficients by the said centred pseudo-random sequence (w) in order to insert the same information bit on the said set of coefficients; and checking (E504–E508), over each region, of a criterion of detectability of the information bit inserted by modulation. Use especially for determining an adaptative partition as a function of a criterion of detectability of an information bit inserted on each region.

摘要： Motion vectors of a first reference frame are permitted to point to a plurality of further reference frames. A method of storing the motion vectors comprises, when a block of the first reference frame has two motion vectors initially, selecting one of the two motion vectors, the non-selected motion vector not being stored. The selected motion vector may be scaled. This can reduce the motion vector memory size.

摘要： Reference prediction mode values, also referred to as most probable modes, usable for encoding or decoding of a prediction mode related to a current coding unit, are derived. First and second reference prediction mode values are derived (S402) from respective prediction modes of at least two neighboring coding units of the current coding unit. The first and second reference prediction modes are different. A third reference prediction mode value is derived (S403) from the first and second reference prediction mode values. The third reference prediction mode is different from each of said first and second reference prediction mode values.By deriving three MPMs instead of two for comparison with the prediction mode of the current coding block the coding efficiency is improved. This is due to the increase in the probability that the prediction mode of the current coding block corresponds to one of the derived most probable modes.

摘要： A temporal motion vector predictor is includable, together with one or more spatial motion vector predictors, in a set of motion vector predictors for a block to encode of a current frame. A method of determining the temporal motion vector predictor comprises selecting as the temporal predictor one motion vector from among motion vectors in a reference block of a reference frame different from the current frame. The reference block is a block of the reference frame collocated with the block to encode or a block of the reference frame neighboring the collocated block. The selection is based on a diversity criterion for achieving diversity among the predictors of the set.This can reduce the motion vector memory requirements with no or no significant additional coding efficiency penalty. Alternatively, even if the motion vector memory is not reduced in size, coding efficiency improvements can be achieved.

摘要： The present invention concerns a method of coding a plurality of digital image signals in a bitstream, said signals each corresponding to a view of a scene, the said coding method comprising the use of a pre-determined predictive coding structure, the views being associated with input views in the coding structure. The coding method according to the invention comprises, for at least one pair of views of the scene, steps of determining a spatial intersection zone (E44) and of calculating a value representing the similarity between the signals corresponding to said views (E45), according to at least some of the signals contained in said spatial intersection zone. These steps are followed by a step of associating (E46) at least one view with an input view of the predictive coding structure according to at least one calculated similarity value. The invention applies both to fixed image signals and to image sequences.
