摘要： To preserve backward compatibility with a non-HDR device or service, an HDR picture may be represented using a modulation value and an SDR picture representative of the HDR picture. The modulation value and the SDR picture can then be encoded into the bitstream. At the receiving side, the modulation value and the SDR picture can be decoded. Based on the modulation value, the SDR picture can be mapped to a decoded HDR picture. For a non-HDR device or service, the modulation value information may be discarded and only the SDR picture is decoded. In particular, the modulation value may be explicitly signaled through an SEI (Supplemental Enhancement Information), a Parameter Set (PPS or SPS), a header, or a VUI (Video Usability Information).

摘要： The invention involves a method for coding using a parametric motion model of which the parameters are defined from the motion data of the causal neighbourhood. Specifically, the method for coding a current block (B) comprises the following steps:
- determine (E1) a prediction block of the current block from a motion model defined by a set of parameters, the model associating a motion vector pointing at a pixel of a prediction block with each pixel of the current block.
- calculate (E2) a residual block between the current block and the prediction block, and
- code (E3) the residual block.
According to the invention, the parameters of the motion model are determined from the motion data associated with the causal neighbourhood blocks (VC) of the current block. Therefore, they can be deducted from parts of images already coded and do not need to be incorporated in the image data stream.

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 video encoding using geometry adaptive block partitioning is described.
The method comprises the steps of using a current video image for determining a spatio-temporal gradient image, using the determined spatio-temporal gradient image for estimating occurrence frequencies of block partitioning parameter pairs; selecting a predetermined number of block partitioning parameter pairs, the selected block partitioning parameter pairs being the most frequent occurring block partitioning parameter pairs; and encoding blocks of the current video image using one of the selected block partitioning parameter pairs.
Since the estimates of occurrence frequencies are determined using a spatio-temporal gradient image determined using the current video image, the parameter pairs dynamically pre-selected as available for encoding of the current video image are adapted to moving object boundaries depicted in the current video image. In encoding of boundaries of moving objects, geometry adaptive block partitioning provides the most encoding gain.
