对视差运动向量的导出、使用这种导出的3D视频编码和解码
Abstract:
本发明涉及一种用于对当前图像(Ik)进行解码的方法，该当前图像包括分别代表同一场景的至少两个视图，所述解码方法包括对视差运动向量的导出步骤(D3)，所述解码方法的特征在于，在所述导出步骤过程中其包括在于以下各项的步骤：构造(S1)至少一个视差运动向量列表(L1)，在该列表中，已经分别根据两种不同的估计方法得到了至少两个视差运动向量，将函数应用(S3)到所述列表的所述至少两个视差运动向量。这种方法适用于MVV或MVD类型的当前图像Ik。
Abstract(English):

The invention relates to a method of decoding a current image (Ik) comprising at least two views which are respectively representative of one and the same scene, said decoding method comprising a step (D3) of deriving a disparity motion vector, said decoding method being characterized in that, in the course of said deriving step, it comprises the steps consisting in: - constructing (S1) at least one list (L1) of disparity motion vectors, in which at least two disparity motion vectors have been obtained respectively according to two different estimation procedures, - applying (S3) a function to said at least two disparity motion vectors of said list. Such a method is applicable to a current image U of MVV or MVD type.
