摘要： The invention relates to a predictive coding/decoding method/device for a group of pictures belonging to a sequence of images, using at least one reference image belonging to a group of pictures other than the group of pictures to code, and converting the values of the pixels of the images of the group of pictures from a configurable transform such that these values are expressed in a target dynamic. The method is characterised in that it converts the values of the pixels of each reference image from the transform thus configured identically to the one used to convert the values of the pixels of the images of the group of pictures to code.

摘要： The invention is made in the field of HDR video image encoding and decoding. A method for encoding an HDR video image of high dynamic range using LDR video images is described. The LDR video images provide differently exposed lower dynamic range depictions of the HDR video content and wherein the LDR video images are encoded as different views of a multi-view coding scheme. The method described comprises using processing means for selectively pre-processing, prior to encoding, one of the LDR video images according to a parameterized pre-processing parameterized according to at least one parameter encoded in metadata. This allows to better compensate for the effects of different exposures and enables efficient inter-exposure prediction.

摘要： A method for performing super-resolution of a single image comprises steps of downsampling (S 1 ) a LR input image by a first factor, separating the LR input image into overlapping blocks (x i ), and for each of the blocks (x i ) searching similar blocks in the downsampled LR images, determining blocks (c i , 1 ,c i , 2 ,c i , 3 ) at corresponding positions in the LR input image, locally optimizing (S 4 ) the blocks by linear approximation to obtain locally optimized patches (z k a ), downsampling (S 5 ) the locally optimized patches (z k a ) by the first factor to obtain a downsampled locally optimized patch (z k a,d ), comparing the downsampled locally optimized patch (z k a,d ) with the input block ( x i 0 ) and optimizing the number and/or weights (w i,1 ,w i,2 ,w i,3 ) of the determined blocks (c i , 1 ,c i , 2 ,c i , 3 ), wherein a locally optimized patch (x 1 i ) is obtained, and repeating the above steps with different sampling factors, wherein for each repetition the locally optimized patch (x 1 i , x 2 i , x 3 i ) of the previous iteration is used as input block. The locally optimized patch (x 3 i ) of the last iteration are accumulated and averaged (S 8 ), and IBP (S 9 ) is performed to obtain a HR output image (S 10 ).

摘要： A content stream comprising video and synchronized illumination data is based on a reference lighting setup from, for example, the site of the content creation. The content stream is received at a user location where the illumination data controls user lighting that is synchronized with the video data, so that when the video data is displayed the user's lighting is in synchronization with the video. In one embodiment, the illumination data is also synchronized with events of a game, so that a user playing games in a gaming environment will have his lighting synchronized with video and events of the game. In another embodiment, the content stream is embedded on a disk.
