摘要： In scalable video coding, Enhancement Layer (EL) pictures are usually predicted from decoded Base Layer (BL) pictures. When the EL pictures and the BL pictures are represented with different color spaces, transforming the decoded BL pictures, for example, to the color space of the EL may improve the prediction. To accurately predict from the BL, the color space of the BL pictures can be partitioned into multiple octants, wherein each octant is associated with a respective set of color mapping function (CMF) parameters. In one embodiment, we propose to estimate the CMF parameters for one particular octant based on not only samples from the particular octant but also samples from neighboring octants in order to reduce color discontinuity artifacts.
摘要翻译：在可伸缩视频编码中，增强层（EL）图像通常从解码的基本层（BL）图像预测。当EL图像和BL图像用不同的颜色空间表示时，例如将解码的BL图像变换到EL的颜色空间可以改善预测。为了从BL准确预测，BL图像的颜色空间可以被划分成多个八分圆，其中每个八分圆与相应的一组颜色映射函数（CMF）参数相关联。在一个实施例中，我们建议基于不仅来自特定八分圆的样本，而且基于来自相邻八分圆的样本，来估计一个特定八分圆的CMF参数，以便减少颜色不连续的伪像。

摘要： The invention relates to a method for modelling a scene from a plurality of maps representative of depth, each map representative of depth being associated with a view of the said scene according to a particular viewpoint (410, 420). To optimize the fidelity and precision of the scene modelling, the method comprises the following steps:
- generating, for each map representative of depth, a surface (31, 32) representative of the said depth map in world space;
- estimating a volume bounding all surfaces (31, 32) generated, the said bounding volume being discretised into a plurality of voxels;
- associating attributes representative of transparency with the said voxels of the bounding volume; and
- generating a resulting surface according to the attributes representative of transparency associated with the said voxels.
The invention also relates to a device for processing the data representative of the corresponding depth.
