摘要： The present principles relates to a method and device for reconstructing an HDR image by applying a reconstruction process on a SDR image whose the content is similar to the content of the HDR image but the dynamic range of the luminance values of said SDR image is lower than the dynamic range of the luminance values of said HDR image, said reconstruction process requiring parameters obtained from a bitstream. The method is characterized in that the method further comprises determining whether all the required parameters are available from the bitstream and recovering the lost or corrupted parameters from additional data, said reconstruction process further taking into account said recovered parameters.

摘要： The present disclosure generally relates a method and device for processing color image data. The method comprises a color gamut mapping in the course of which a color image data (CID), represented by a first 2D point (A) belonging to a representation of the original color gamut in a chromaticity diagram, is mapped to a mapped color image data (MCID) of a target color gamut (TCG), the mapped color image data of the target color gamut (TCG) being represented by a second 2D point (B) belonging to a representation of the target color gamut (TCG) in the chromaticity diagram, wherein the color gamut mapping comprises: —obtaining (100) a representation of a preserved color gamut (PCG) in the chromaticity diagram by applying an homothety either to the original color gamut or to the target color gamut; —checking (110) if said first 2D point is located outside the representation of the preserved color gamut (PCG); and —when said first 2D point is located outside the representation of the preserved color gamut (PCG), moving (300) said first 2D point so that it belongs to the representation of the target color gamut (TCG), the second 2D point being then equal to the moved first 2D point. The disclosure relates also to a method and device for encoding/decoding color image data.

摘要： The method for inheriting coding data implements the following steps : - superimposition (4), after zooming and for the common video part, of an image (F2) (101) of low resolution onto an image (F1) (102) of higher resolution, - determination (61) of the number of zoomed BR blocks of F2 covering a HR block of F1, - if this number equals 1 (64), assignment of the mode and motion data (65) of the zoomed BR block to this HR image block, - if this number is greater than 1, assignment of a mode and of motion data (66) as a function of the modes and the motion data of the zoomed BR blocks covering this HR block, - merging neighbouring HR blocks depending on the similarity of the motion data and/or of the coding modes assigned to the HR blocks and assignment of the coding modes and motion data to the new blocks according to the coding modes and motion data of the merged blocks.

摘要： The invention relates to a method for coding a current block comprising an iterative step of decomposition into atoms of a first dictionary of a vector of data comprising at least reconstructed image data associated with pixels situated in a causal neighbouring area of a current block. At each iteration, the step of decomposition into atoms comprises the following steps for: - selecting (32) a first atom in the first dictionary of atoms, - applying (34, 340) a phase correlation between a patch associated with the first atom and a current residue vector, when the first atom is a textured atom, - extracting (34, 342) from the patch at least the part most correlated with the residue vector, the extracted part forming a second atom, - selecting (36) from among the first atom and the second atom, the atom most correlated with the current residue vector, and - updating (38) the residue vector according to the selected atom.

摘要： The invention is related to a method for determining a filter for interpolating one or more pixels comprised in a frame. The proposed method comprises the step of determining the filter based on other pixels in the remainder of the frame wherein a motion vector associated with said pixels has at least one motion parameter in common with another motion vector associated with said other pixels and the filter is determined such that a quality of an interpolation of said other pixels, said interpolation being determined by help of said determined filter, reaches or exceeds the quality of any other interpolation of said other pixels determinable by help of one of different filter candidates comprised in a filter candidate set. In determining the filter solely on different other pixels of the same frame, said method for determining a filter for interpolation allows for realization of a single pass encoding framework.

摘要： Often hierarchical bi-directionally predicted (B-) frame structures are used for encoding a video picture sequence. The frames may consist of interlacing fields. A method for encoding interlaced video, wherein inter-prediction of fields is used and reference lists are assigned to the fields for indicating reference frames or fields, comprises that, if within such reference list a reference to another frame is included, then references (fwd6O, fwd61) to both fields (4,4') of the other frame are included separately in direct sequence. Further, a temporal level is assigned to each of the frames according to their display order, and for the frames of all except one temporal level the quantization parameter is higher for one type (top) of fields than for the other type (bottom) of fields.
