Abstract: A method is provided for encoding a sequence of images generating a data stream in the form of a structure of embedded data layers of n successive levels each of which corresponds to the predetermined resolution of said images. Said method comprises an encoding stage, which encodes at least one of said layers of an n+1 level by prediction on the basis of said level n layer and encodes each data layer of the level n in the form of a base sub-stream and, optionally, in the form of at least one enhancement sub-stream enabling to obtain at least one version of the enhanced quality of said images. The method also encodes, for at least one data layer of the n level, at least one single sub-stream enabling to reconstruct the version of said images at said level n resolution with a quality higher than said enhanced qualities, wherein said single sub-steam of the level n layer is not used during the prediction encoding of the layers of a level other than the level n.

Abstract: A motion field between a destination image and a source image is densified on the basis of the motion field between the source image and the destination image. Connections between the source image pixels or subpixels (X11, X111, X12, X121) and the destination image pixels or subpixels (B, C′, E, F) are determined. For each pixel or subpixel of the destination image connected to a pixel or subpixel of the source image, a pixel or subpixel association space (Fen) including one pixel or subpixel of the destination image is determined. Each pixel or subpixel in the association space (A, A′, B, B′, C, C′) is associated with the source image pixel (X11) connected to the pixel or subpixel to form a dense motion field between the destination and source images.

Abstract: The invention concerns a method of coding a set of data (IM) representing physical quantities, characterized in that it includes the steps of: decomposing (E20) the set of data into a plurality of frequency sub-bands on at least one resolution level, then, for each resolution level, segmenting (E23, E26) at least one sub-band into at least two homogeneous regions, in order to form a segmentation map, ordering (E30, E33) the regions according to a predetermined criterion, coding (E21) the sub-bands of the resolution level under consideration, ordering (E31, E34) the coding data of the sub-bands as a function of the order of the regions.

Abstract: According to the invention, the method of primary processing of a first set of primary data (IM,f) representing physical quantities includes: a set division step (200A to 202) during which the first set of data is divided into sub-sets of first data, and for each first sub-set of data: a step (205 to 207) of “constructing” a global contractive mapping of the first type, for the said first sub-set of data, whose fixed point constitutes an approximation of all or part of this sub-set. The set of parameters (ai, b) thus determined constitutes a primary representation of the said first set of data.
