Fig. 1 shows the schematic diagram of asymmetrical movement partitioning scheme AMP in cataloged procedure.

Coding and decoding video structure includes three kinds of units：Coding unit（Coding Unit,CU）, predicting unit （Prediction Unit,PU）And converter unit（Transform Unit,TU）.Wherein, PU includes being used to predict the pre- of process Block and the content information (such as reference key, motion vector etc.) of prediction block are surveyed, generally there are four kinds of symmetrical PU partitioning schemes：2N× 2N, 2N × N, N × 2N and N × N.In order to further improve code efficiency, on the basis of original four kinds symmetrical PU partitioning schemes On, newly increase asymmetrical movement partitioning scheme AMP.I.e. as shown in Figure 1, during interframe encode, CU have 2N × nU, 2N × ND, nR × 2N and the asymmetric PU partitioning schemes of tetra- kinds of nL × 2N.

When being encoded to 3D videos, for each viewpoint, it is necessary to be encoded respectively to depth map and texture maps.In frame Between in cataloged procedure, usually using a viewpoint as basic viewpoint（Base View）, using other viewpoints as non-basic viewpoint. The coding mode different from other viewpoints can be used to the basic viewpoint, for example with traditional efficient video coding（High Efficiency Video Coding, HEVC）Mode.And during to non-basic viewpoint coding, can be with order to improve code efficiency With reference to the coding information of basic viewpoint, and in addition to using tradition HEVC modes, more coding toolses, such as parallax are mended Repay Predicting Technique, difference vector acquiring technology, depending on a motion prediction, depending on a residual prediction, luminance compensation, View Synthesis prediction Deng can be applicable in the cataloged procedure of non-basic viewpoint.

To each in four kinds of asymmetric PU partitioning schemes of every CU of each viewpoint, it is thus necessary to determine that it is using just Normal Normal modes carry out code detection and still carry out code detection using merging Merge modes.

It is to be understood that the embodiment of the present invention carries out code detection using Normal modes, refer to pre- using complete movement Survey compensation way and carry out code detection.

Fig. 2 shows the schematic stream of the method 100 of asymmetrical movement partitioning scheme coding according to embodiments of the present invention Cheng Tu, this method 100 can be performed by encoding device.

S101, determines coding unit CU；

S102, the non-basic viewpoint that the CU is texture maps CU and according to the size of the CU, the CU it is current optimal pre- Survey unit PU partitioning schemes, the CU current optimal PU partitioning schemes coding mode and optimal PU points of upper level CU of the CU Mode is cut, determines that the first asymmetric PU partitioning schemes of the CU do not meet the first coding mode Rule of judgment, and meet second During coding mode Rule of judgment, the reference view information depending between of the viewpoint according to belonging to the CU determines the first asymmetric PU of the CU The code detection mode of partitioning scheme.

, therefore, the method for the asymmetrical movement partitioning scheme coding of the embodiment of the present invention, by determining respectively to texture The code detection mode that the coding unit CU of figure, the basic viewpoint of depth map and non-basic viewpoint is taken, and reference is joined depending between The code detection mode that view information determines the CU of non-basic viewpoint is examined, code efficiency can be effectively improved.

In the embodiment of the present invention, basic viewpoint is also referred to as independent viewpoint, is the viewpoint encoded first.

Specifically, in S101, the current coding unit CU encoded is determined.In S102, carried out to the CU During coding, encoding device determines whether coding is in interframe encode process first.After determining that coding is in interframe encode process, Encoding device determines to be presently at texture maps cataloged procedure or depth map encoding process.In the embodiment of the present invention, alternatively, Encoding device determines to be currently at the cataloged procedure of texture maps, and determines that the viewpoint belonging to the CU is non-basic viewpoint.

Further, according to the size of the CU, the current optimum prediction unit PU partitioning schemes of the CU, the CU at present most The coding mode of excellent PU partitioning schemes, determines that the first asymmetric PU partitioning schemes of the CU do not meet the first coding mode and judge bar Part.

Specifically, as one embodiment, the size of the CU is not 64 × 64, and the current optimum prediction unit of the CU PU partitioning schemes are 2N × N, then asymmetric PU the partitioning schemes 2N × nU and 2N × nD that can determine the CU are to meet the first volume Code mode Rule of judgment；Alternatively, the size of the CU is not 64 × 64, and the current optimum prediction unit PU partitioning schemes of the CU For 2N × 2N, and the coding mode of the current optimum prediction unit PU partitioning schemes of the CU is not merge or skip patterns, then Asymmetric PU the partitioning schemes 2N × nU and 2N × nD that can also determine the CU are to meet the first coding mode Rule of judgment.

Alternatively, as another embodiment, the size of the CU is not 64 × 64, and the current optimum prediction unit of the CU PU partitioning schemes are N × 2N, then asymmetric PU the partitioning schemes nL × 2N and nR × 2N that can determine the CU are to meet the first volume Code mode Rule of judgment；Alternatively, the size of the CU is not 64 × 64, and the current optimum prediction unit PU partitioning schemes of the CU For 2N × 2N, and the coding mode of the current optimum prediction unit PU partitioning schemes of the CU is not merge or skip patterns, then Asymmetric PU the partitioning schemes nL × 2N and nR × 2N that can also determine the CU are to meet the first coding mode Rule of judgment.Instead It, then not meet the first coding mode Rule of judgment.

According to the current optimum prediction unit PU partitioning schemes of the CU, the coding staff of the current optimal PU partitioning schemes of the CU The optimal PU partitioning schemes of the upper level CU of formula and the CU, determine that the first asymmetric PU partitioning schemes of the CU meet the second coding Mode Rule of judgment.

Specifically, as one embodiment, the current optimal PU partitioning schemes of the CU are 2N × 2N, and the CU's is current The coding mode of optimal PU partitioning schemes is not skip coding modes；Alternatively, the optimal PU partitioning schemes of the upper level CU of the CU For AMP modes；Alternatively, the current optimal PU partitioning schemes of the CU are 2N × N, and the optimal PU segmentations of the upper level CU of the CU Mode is non-PU partitioning schemes, then asymmetric PU the partitioning schemes 2N × nU and 2N × nD that can determine the CU are to meet the second volume Code mode Rule of judgment.

Alternatively, as another embodiment, the current optimal PU partitioning schemes of the CU are 2N × 2N, and the CU's is current The coding mode of optimal PU partitioning schemes is not skip coding modes；Alternatively, the optimal PU partitioning schemes of the upper level CU of the CU For AMP modes；Alternatively, the current optimal PU partitioning schemes of the CU are N × 2N, and the optimal PU segmentations of the upper level CU of the CU Mode is non-PU partitioning schemes, then asymmetric PU the partitioning schemes nL × 2N and nR × 2N that can determine the CU are to meet the second volume Code mode Rule of judgment.Conversely, it is then not meet the second coding mode Rule of judgment.

It is to be understood that in embodiments of the present invention, the first asymmetric PU partitioning schemes of the CU do not meet the first coding mode Rule of judgment, meets the second coding mode Rule of judgment.In addition to the first asymmetric PU partitioning schemes, the CU's is other asymmetric PU partitioning schemes can meet the first coding mode Rule of judgment；The first coding mode Rule of judgment can not also be met, met Second coding mode Rule of judgment；The first coding mode Rule of judgment can not also be both met, does not meet the second coding mode yet Rule of judgment.Different according to judging result, its code detection mode finally taken may be different, the embodiment of the present invention to this not It is construed as limiting.

The first coding mode Rule of judgment is not met in the first asymmetric PU partitioning schemes for determining the CU, meets the second volume After code mode Rule of judgment, the reference view information depending between of the viewpoint according to belonging to the CU determines the first asymmetric PU of the CU The code detection mode of partitioning scheme.Wherein, the reference view depending between of the viewpoint belonging to the CU can be basic viewpoint, can also It is non-basic viewpoint.It can include the coding mode of CU and the symmetrical PU of the CU of reference view between regarding depending on a reference view information Partitioning scheme.3rd coding mode Rule of judgment is the Rule of judgment based on reference view information between above-mentioned regard.

Specifically, as one embodiment, the optimal PU partitioning schemes of CU of a reference view are regarded as 2N × N；Alternatively, regard Between reference view CU optimal PU partitioning schemes be 2N × 2N and between regarding the CU of reference view coding mode not as merge Or skip patterns, then it can determine that asymmetric PU the partitioning schemes 2N × nU and 2N × nD of the CU sentence to meet the 3rd coding mode Broken strip part.

Alternatively, as another embodiment, the optimal PU partitioning schemes of CU of a reference view are regarded as N × 2N；Alternatively, regard Between reference view CU optimal PU partitioning schemes be 2N × 2N and between regarding the CU of reference view coding mode not as merge Or skip patterns, then it can determine that asymmetric PU the partitioning schemes nL × 2N and nR × 2N of the CU sentence to meet the 3rd coding mode Broken strip part.Conversely, it is then not meet the 3rd coding mode Rule of judgment.

Alternatively, the judgement of the 3rd coding mode is met as one embodiment, the first asymmetric PU partitioning schemes of the CU During condition, code detection is carried out using Normal modes to the first asymmetric PU partitioning schemes of the CU.

Alternatively, the 3rd coding mode is not met as another embodiment, the first asymmetric PU partitioning schemes of the CU During Rule of judgment, code detection is carried out using Merge modes to the first asymmetric PU partitioning schemes of the CU.

Below in conjunction with specific example, method 100 is illustrated.

In video coding process, the CU of 16 × 16 sizes of a non-basic viewpoint of texture maps is encoded.Should 2N × the nU and 2N × nD of CU does not meet the first Rule of judgment, meets the second Rule of judgment.On this basis, the CU is then judged 2N × nU and 2N × nD do not meet the 3rd Rule of judgment, then 2N × the nU and 2N × nD of the CU are carried out using Merge modes Code detection.If 2N × the nU and 2N × nD of the CU are not meeting the first Rule of judgment, meet the second Rule of judgment ground foundation On, meet the 3rd Rule of judgment, then coding inspection is carried out using Normal modes to the 2N × nU and 2N × nD of the non-basic viewpoint Survey.

Fig. 2 is the CU for the non-basic viewpoint that CU is texture maps, and the first asymmetric PU partitioning schemes of the CU are not met First Rule of judgment, meets the explanation of the situation of the second Rule of judgment.In embodiments of the present invention, for the non-of texture maps The CU of basic viewpoint, one kind in its four kinds asymmetric PU partitioning schemes may meet the first coding mode Rule of judgment.Accordingly Ground, this method 100 can also include：

In the non-CU of viewpoint substantially that the CU is texture maps and according to the size of the CU, the current optimal PU segmentation sides of the CU Formula, the CU current optimal PU partitioning schemes coding mode and the CU upper level CU optimal PU partitioning schemes, determine should When the first asymmetric PU partitioning schemes of CU meet the first coding mode Rule of judgment, to the first asymmetric PU segmentation sides of the CU Formula carries out code detection using Normal modes.

Specifically, determine the CU for the non-basic viewpoint that the CU is texture maps, and determine the first asymmetric PU of the CU When partitioning scheme meets the first coding mode Rule of judgment, Normal modes are used to the first asymmetric PU partitioning schemes of the CU Carry out code detection.For example, the CU of 16 × 16 sizes of basic viewpoint non-to one of texture maps is encoded, the nL of the CU × 2N and nR × 2N meets the first Rule of judgment, then carries out coding inspection using Normal modes to the nL × 2N and nR × 2N of the CU Survey.

It is to be understood that the CU of asymmetric PU partitioning schemes to(for) a non-basic viewpoint of texture maps, it may both not be inconsistent The first coding mode Rule of judgment is closed, does not also meet the second coding mode Rule of judgment, at this time, not to the asymmetric PU of the CU Partitioning scheme carries out code detection.

The CU of the non-basic viewpoint of texture maps is illustrated above.In embodiments of the present invention, texture maps further include The CU of basic viewpoint, one kind in its asymmetric PU partitioning scheme may not meet the first coding mode Rule of judgment, meet the Two coding mode Rule of judgment.Correspondingly, this method 100 can also include：

In the CU for the CU of the basic viewpoint of texture maps and according to the size of the CU, the current optimal PU segmentation sides of the CU Formula, the CU current optimal PU partitioning schemes coding mode and the CU upper level CU optimal PU partitioning schemes, determine should The first asymmetric PU partitioning schemes of CU do not meet the first coding mode Rule of judgment, and meet second coding mode and sentence During broken strip part, code detection is carried out using Normal modes to the first asymmetric PU partitioning schemes of the CU.

Specifically, determine the CU for the basic viewpoint that the CU is texture maps, and determine the first asymmetric PU points of the CU The mode of cutting does not meet the first coding mode Rule of judgment, non-right to the first of the CU when meeting the second coding mode Rule of judgment PU partitioning schemes are claimed to carry out code detection using Normal modes.For example, big to the 32 × 32 of a basic viewpoint of texture maps Small CU is encoded, and the 2N × nU and 2N × nD of the CU do not meet the first Rule of judgment, meet the second Rule of judgment, then to this 2N × the nU and 2N × nD of CU carries out code detection using Normal modes.

Above is CU is the basic viewpoint of texture maps, and the asymmetric PU partitioning schemes of the CU do not meet the first judgement bar Part, meets the explanation of the situation of the second Rule of judgment.In embodiments of the present invention, for the basic viewpoint of texture maps CU, one kind in its four kinds asymmetric PU partitioning schemes may meet the first coding mode Rule of judgment.Correspondingly, this method 100 can also include：

In the CU for the CU of the basic viewpoint of texture maps and according to the size of the CU, the current optimal PU segmentation sides of the CU Formula, the CU current optimal PU partitioning schemes coding mode and the CU upper level CU optimal PU partitioning schemes, determine should When the first asymmetric PU partitioning schemes of CU meet the first coding mode Rule of judgment, the first asymmetric PU of the CU is split Mode carries out code detection using Normal modes.

Specifically, determine the CU for the basic viewpoint that the CU is texture maps, and determine the first asymmetric PU segmentations of CU When mode meets the first coding mode Rule of judgment, the first asymmetric PU partitioning schemes of the CU are carried out using Normal modes Code detection.For example, the CU of 32 × 32 sizes of a basic viewpoint of texture maps is encoded, the nL × 2N and nR of the CU × 2N meets the first Rule of judgment, then carries out code detection using Normal modes to the nL × 2N and nR × 2N of the CU.

It is to be understood that the CU of asymmetric PU partitioning schemes to(for) a basic viewpoint of texture maps, it may both not meet First coding mode Rule of judgment, does not meet the second coding mode Rule of judgment yet, at this time, not to the asymmetric PU points of the CU The mode of cutting carries out code detection.
