背景技术
JCT3V (Joint Collaborative Team on 3D Video Coding , 3DV视频编码 联合工作组）支持腿 11 i -V i ews (多视， 即 2个或以上） 的编码。 多视是指对 同一场景从不同视角进行釆集的视频序列， 其中， 各个视之间存在较强的相 关性。 利用各个视 ( view)之间的相关性， 通过 inter-view prediction (视 间预测）技术去除视间冗余， 提高编码压缩性能。
inter-view predict ion技术可以包括：
利用参考视的 MV (Motion Vector, 运动矢量）作为参考， 对当前 view 进行预测编码， 即 inter-view MV prediction视间 MV预测技术。
在 Inter-view MV predict ion技术中， 其实现步骤可以包括：
1.基于空域、 时域相邻块获取当前预测块的 DV (Disparity vector, 视差 矢量）预测值。 这个过程可以称为 DV derivation process (视差矢量导出过 程）， 即获取 DV预测值的过程；
2.利用获取到的 DV预测值从参考视中获取当前预测块的一个 MV/DV预测 值， 该 MV/DV预测值是基于参考视获取的， 可以称为视间 MV/DV预测值；
3.利用获得的 MV/DV预测值， 与其他 MV/DV预测值（视内的 )进行多运 动矢量竟争。
下面对获取 DV预测值的过程进行举例说明。
如图 1所示， 与当前 PU (Prediction Unit, 预测单元〈以下可称为预测 块〉）在空域上的相邻块可以包括： 相邻块 AO (当前 PU左下角位置对应的左 下相邻块）、 相邻块 A1 (当前 PU左下角位置对应的左边相邻块）、 相邻块 B0
(当前 PU右上角位置对应的右上相邻块）、相邻块 B1 (当前 PU右上角位置对 应的上边相邻块）、 相邻块 B2 (当前 PU左上角位置对应的左上相邻块）； TDVP
( Tempora l Di spar i ty vector pred ictor , 视差矢量时域予贞测值)为当前 PU 在时域上相应的视差矢量预测值。
具体获取 DV预测值的步骤可以包括：
依次检测各相邻块中的 DV信息是否存在， 如果不存在， 则继续检查下一 相邻块； 如果存在， 则从该相邻块中获取当前 PU的 DV预测值。
具体的检测顺序可以为但不限于： 预测块 Al->预测块 Bl->预测块 B0-> 预测块 A0->预测块 B2->TDVP;先检查预测块 A1是否存在 DV信息，如果存在， 则从预测块 A1中获取当前 PU的 DV预测值； 如果不存在， 则检测预测块 B1 , 依照上述顺序依次进行检测， 直到获取到 DV预测值， 后续步骤不再赘述。
进一步的， 当前 CU ( Coding Uni t , 编码单元）可以包含至少两个 PU, 釆用串行方式获取至少两个 PU的 DV预测值， 即获取到当前 PU的 DV预测值 后， 才开始获取下一个 PU的 DV预测值。
在实现上述预测块的视差矢量预测值获取的过程中， 发明人发现现有技 术中至少存在如下问题： 若当前 CU包含至少两个 PU, 这至少两个 PU之间存 在依赖性， 只能釆用串行方式获取至少两个 PU的 DV预测值， 降低了并行处 理的能力。 发明内容

具体实施方式
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而 不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作 出创造性劳动前提下所获得的所有其他实施例 , 都属于本发明保护的范围。
现有技术中， 当前 CU可以包含至少两个 PU, 釆用串行方式获取至少两个 PU的 DV预测值， 即获取到当前 PU的 DV预测值后， 才开始获取下一个 PU的 DV预测值。
具体的可以包括：
如图 2a至图 2g所示， 一个 CU (图中的实现框）可以进一步划分成多个 PU, 在 HEVC (High Efficiency Video Coding, 高效视频编码标准） 中， CU 可以有 7种 partition (划分）方式。 如图 2a至图 2c中的 partition方式是 把当前 CU划分成左右 2个 PU (PU1和 PU2), 又如图 2d的 partition方式是 把当前 CU划分成 4个 PU (PU1、 PU2、 PU3、 PU4 ), 其他类型不再赞述。
以图 2a所示的 partition为例，由于，PU2的空域相邻块 A1位于 PU1内， 因此， 只有当 PU1编码结束后， 才可以开始获取 PU2的 DV预测值， 釆用串行 方式获取 PU1与 PU2的 DV预测值。 具体的可以为， 首先， 按照上述方法获取 PU1的 DV预测值， 然后， 按照上述方法获取 PU2的 DV预测值。
这样， 使得获取至少两个 PU的 DV预测值的速度较慢， 降低压缩编码的 性能。 为了解决上述获取同一编码单元中的至少两个 PU的 DV预测值的速度较 慢， 降低压缩编码的性能的问题， 本实施例提供一种预测块的视差矢量预测 值获取的方法， 如图 3所示， 可以包括：
301、 获取当前预测块空域上的相邻块；
302、 根据当前编码单元的划分方式、 当前预测块在当前编码单元中的位 置以及相邻块的位置， 确定相邻块是否位于当前编码单元中；
303、 按照预设顺序从不位于当前编码单元中的相邻块中获取视差矢量预 测值， 直到获取到一个视差矢量预测值后停止获取。
釆用上述方案后， 获取当前预测块空域上的相邻块； 根据当前编码单元 的划分方式、 当前预测块在当前编码单元中的位置以及相邻块的位置， 确定 相邻块是否位于当前编码单元中； 按照预设顺序从不位于当前编码单元中的 相邻块中获取视差矢量预测值， 直到获取到一个视差矢量预测值后停止获取。 这样， 可以并行获取同一编码单元中的至少两个预测块的视差矢量预测值， 增加了获取同一编码单元中的至少两个预测块的视差矢量预测值的速度， 进 而提高了并行处理能力。
本实施例提供另一种预测块的视差矢量预测值获取的方法， 该方法是对 图 3所示的方法的进一步扩展， 如图 3所示， 具体的可以包括：
301、 获取当前预测块空域上的相邻块。
进一步的， 如图 1 所示， 获取的当前预测块空域上的相邻块可以包括： 位于当前预测块左下侧的相邻块 AO , 位于当前预测块左侧的相邻块 A1 , 位于 当前预测块右上侧的相邻块 B0 , 位于当前预测块上侧的相邻块 B1 , 位于当前 预测块左上侧的相邻块 B2。
302、 根据当前编码单元的划分方式、 当前预测块在当前编码单元中的位 置以及相邻块的位置， 确定相邻块是否位于当前编码单元中。
进一步的， 如图 2a至图 2c所示， 若当前编码单元的划分方式为： 当前 编码单元被左右划分为第一预测块和第二预测块， 并且当前预测块为第二预 测块， 则确定当前预测块的相邻块 A1位于当前编码单元中； 进一步的， 如图 2e至图 2g所示， 若当前编码单元的划分方式为： 当前 编码单元被上下划分为第一预测块和第二预测块， 并且当前预测块为第二预 测块， 则确定当前预测块的相邻块 B1位于当前编码单元中。
进一步的， 如图 2d所示， 若当前编码单元的划分方式为： 当前编码单元 被上下左右划分为位于当前编码单元左上侧的第一预测块 PU1、位于当前编码 单元右上侧的第二预测块 PU2、位于当前编码单元左下侧的第三预测块 PU3以 及位于当前编码单元右下侧的第四预测块 PU4时：
如图 4a所示， 若当前预测块为 PU2 , 则确定当前预测块的相邻块 A1和相 邻块 AO位于当前编码单元中；
如图 4b所示， 若当前预测块为 PU3 , 则确定当前预测块的相邻块 B1和相 邻块 B0位于当前编码单元中；
如图 4c所示， 若当前预测块为 PU4 , 则确定当前预测块的相邻块 Al、 相 邻块 B1和相邻块 B2位于当前编码单元中。
这样， 当 CU被上下左右划分为 PU1、 PU2、 PU3、 PU4 , 在获取视差矢量预 测值时， 只考虑不位于 CU中的预测块， 使得 PU1、 PU2、 PU3、 PU4可以并行 获取各自的视差矢量预测值。
若所有相邻块以及 TDVP中均不包含视差矢量预测值， 则将 PU1的视差矢 量预测值设置为预设视差矢量预测值。
本实施例对预设顺序、 和预设视差矢量预测值不作限定， 可以根据实际 需要进行设定， 例如， 可以按照 HEVC的帧间预测模式中的方式进行设定， 在 此不再赘述。
本实施例对检测视差矢量预测值的方法不作限定， 为本领域技术人员熟 知的技术， 在此不再赘述。
403、 按照预设顺序从不位于当前编码单元中的相邻块中获取视差矢量预 测值， 直到获取到一个视差矢量预测值后停止获取。
进一步的， 预设顺序由前至后依次可以为： 相邻块 Al、 相邻块 Bl、 相邻 块 B0、 相邻块 A0、 相邻块 B2。 进一步的， 按照预设顺序从不位于当前编码单元中的相邻块中获取视差 矢量预测值， 直到获取到一个视差矢量预测值后停止获取可以包括：
判断当前相邻块中是否包含视差矢量预测值； 若包含， 则从当前相邻块 中获取视差矢量预测值； 若不包含， 则按照预设顺序依次从除当前相邻块的 其他未获取过视差矢量预测值的相邻块中获取视差矢量预测值， 直到获取到 一个视差矢量预测值后停止获取。
如图 2a至图 2c所示可以看出， PU2的相邻块中只有 A1位于 PU1内， 因 此， 在根据相邻块获取 PU2的视差矢量预测值时， 不考虑 PU2的相邻块 A1 , 这样， 可以并行获取 PU1与 PU2的视差矢量预测值； 由于， PU1的所有相邻块 均不位于当前编码单元 CU中， 因此， 在根据相邻块获取 PU1的视差矢量预测 值时， 可以考虑 PU1 的所有相邻块， 具体方法与现有技术相同， 且在背景技 术中已进行了描述， 在此不再赘述。
具体的， 当 CU被左右划分为 PU1和 PU2时， 获取 PU2的视差矢量预测值 可以包括： 由于， 不考相邻块 A1 , 因此， 可以但不限于按照如下预设顺序进 行检测： 相邻块 Bl->相邻块 B0->相邻块 A0->相邻块 B2->TDVP。 这样， 可以 釆用并行方式获取相邻块 PU1与相邻块 PU2的视差矢量预测值。
如图 2e至图 2g所示可以看出， PU2的相邻块中只有 B1位于 PU1内， 因 此， 在根据相邻块获取 PU2的视差矢量预测值时， 不考虑 PU2的相邻块 B1 , 这样， 可以并行获取 PU1与 PU2的视差矢量预测值； 由于， PU1的所有相邻块 均不位于当前编码单元 CU中， 因此， 在根据相邻块获取 PU1的视差矢量预测 值时， 可以考虑 PU1 的所有相邻块， 具体方法与现有技术相同， 且在背景技 术中已进行了描述， 在此不再赘述。
具体的， 当 CU被上下划分为 PU1和 PU2时， 获取 PU2的视差矢量预测值 可以包括： 由于， 不考相邻块 B1 , 因此， 可以但不限于按照如下预设顺序进 行检测： 相邻块 A 〉相邻块 B0- >相邻块 AO- >相邻块 B2- >TDVP。 这样， 可以 釆用并行方式获取相邻块 PU1与相邻块 PU2的视差矢量预测值。
如图 4a所示可以看出， PU2的相邻块 A1和相邻块 AO位于当前编码单元 CU内， 因此， 在根据相邻块获取 PU2的视差矢量预测值时， 不考虑 PU2的相 邻块 A1和相邻块 AO , 这样， 可以并行获取 PU1与 PU2的视差矢量预测值； 由 于， PU1的所有相邻块均不位于当前编码单元 CU中， 因此， 在根据相邻块获 取 PU1 的视差矢量预测值时， 可以考虑 PU1 的所有相邻块， 具体方法与现有 技术相同， 且在背景技术中已进行了描述， 在此不再赘述。
具体的， 当 CU被上下左右划分为 PU1、 PU2、 PU3、 PU4时， 如图 4a所示， 若当前预测块为 PU2 , 获取 PU2的视差矢量预测值可以包括： 由于， 不考相邻 块 A1和相邻块 AO , 因此， 可以但不限于按照相邻块 Bl->相邻块 B0->相邻块 B2->TDVP的顺序各相邻块和 TDVP中的视差矢量预测值；
如图 4b所示， 若当前预测块为 PU3 , 获取 PU3的视差矢量预测值可以包 括： 由于， PU3的相邻块 B1和相邻块 B0位于当前编码单元 CU内， 因此， 不 考相邻块 B1和相邻块 B0 , 可以但不限于按照相邻块 Al->相邻块 A0->相邻块 B2->TDVP的顺序各相邻块和 TDVP中的视差矢量预测值。
如图 4c所示， 若当前预测块为 PU4 , 获取 PU4的视差矢量预测值可以包 括： 由于， PU4的相邻块 Bl、相邻块 BO和相邻块 B2位于当前编码单元 CU中， 因此，不考相邻块 Bl、相邻块 BO和相邻块 B2 , 可以但不限于按照相邻块 B0-> 相邻块 A0->TDVP的顺序各相邻块和 TDVP中的视差矢量预测值。
本实施例对才艮据视差矢量预测值进行 Inter-v iew MV pred i c t ion的方法、 和从相邻块中获取视差矢量的方法不作限定， 为本领域技术人员熟知的技术， 在此不再赘述。
釆用上述方案后， 获取当前预测块空域上的相邻块； 根据当前编码单元 的划分方式、 当前预测块在当前编码单元中的位置以及相邻块的位置， 确定 相邻块是否位于当前编码单元中； 按照预设顺序从不位于当前编码单元中的 相邻块中获取视差矢量预测值， 直到获取到一个视差矢量预测值后停止获取。 这样， 可以并行获取同一编码单元中的至少两个预测块的视差矢量预测值， 增加了获取同一编码单元中的至少两个预测块的视差矢量预测值的速度， 进 而提高了并行处理能力。 为了更好的说明本实施例可以达到的有益效果， 下面提供一种基于 3DV 参考软件平台上的仿真结果， 同时， 该仿真结果还可以说明本实施例不会造 成编码性能上的损失， 仿真数据如下表所示： （其中， average—行代表平均 编码 bi t节省， 负数表示有增益）
