摘要： Multi-view video encoding using early Merge mode decision and/or early CU split termination is disclosed. The present invention encodes a current coding block using the Merge/Skip mode without evaluating coding performance for at least one of Inter modes and Intra modes if the coding conditions associated with the current coding block and a neighboring block set of the current coding block are asserted. The coding conditions may correspond to whether the coding performance of the Skip mode is better than the coding performance of 2N×2N Merge mode for the current coding block and whether all blocks in the neighboring block set select the Merge mode or the Skip mode. Similarly, the process of splitting the current coding block into smaller coding blocks can be terminated without evaluating coding performance associated with the smaller coding blocks from splitting the current coding block if some coding conditions are asserted.
摘要翻译：公开了使用早期合并模式决定和/或早期CU分割终止的多视图视频编码。如果与当前编码块相关联的编码条件和当前编码块的相邻块集合被断言，本发明使用合并/跳过模式来编码当前编码块而不评估至少一个Inter模式和Intra模式的编码性能。编码条件可以对应于跳过模式的编码性能是否优于当前编码块的2N×2N合并模式的编码性能以及相邻块组中的所有块是否选择合并模式或跳过模式。类似地，如果确定了一些编码条件，则可以终止将当前编码块分割成较小编码块的处理，而不评估与较小编码块相关联的编码性能，以分割当前编码块。

摘要： A method and apparatus for three-dimensional video encoding and decoding using disparity derived depth prediction are disclosed. Embodiments of the present invention determine a disparity vector related to a collocated texture block in the dependent view and generate converted depth samples from the disparity vector. The generated converted depth samples are used as a predictor or Merge candidate for the current depth block. The Merge candidate corresponding to the converted depth samples can be placed in the merging candidate list at a location before TMVP (temporal motion vector predictor) merging candidate. The converted depth samples can be generated from the disparity vector according to a function of the disparity vector. Information associated with the function can be signaled explicitly to a decoder or derived implicitly by the decoder. One aspect of the present invention addresses simplified disparity to depth conversion, specifically division-free disparity-to-depth conversion.

摘要： A method and apparatus for three-dimensional or multi-view video encoding and decoding using VSP (view synthesis prediction) with uniform sub-block partition are disclosed. For a current texture block comprising multiple partition blocks, the system derives a single partition decision and partitions each partition block of the current texture block into multiples sub-blocks according to the single partition decision. The VSP processing is then applied to each sub-block to derive the inter-view prediction using VSP. The single partition decision is derived using depth samples of the depth block in a reference view.

摘要： A method and apparatus of depth coding using depth modelling mode 1 (DMM1) are disclosed to reduce the wedgelet pattern table size. In one embodiment, a size-reduced wedgelet pattern for a reduced wedgelet pattern table is generated by excluding at least one non-corner adjacent-edge sample for adjacent-edge partition or at least one opposite-edge sample for opposite-edge partition from starting positions or from ending positions. The reduced wedgelet pattern table may also include at least one omitted wedgelet pattern in at least one wedgelet direction category. For the adjacent-edge partition, the starting positions and the ending positions may correspond to every other even non-corner adjacent-edge samples in a first and a second adjacent edges respectively. For the opposite-edge partition, the starting positions correspond to every other even opposite-edge samples in a first opposite edge and the ending positions include all opposite-edge samples in a second opposite edge.

摘要： A method for a three-dimensional encoding or decoding system incorporating restricted sub-PU level prediction is disclosed. In one embodiment, the sub-PU level prediction associated with inter-view motion prediction or view synthesis prediction is restricted to the uni-prediction. In another embodiment, the sub-PU partition associated with inter-view motion prediction or view synthesis prediction is disabled if the sub-PU partition would result in sub-PU size smaller than the minimum PU split size or the PU belongs to a restricted partition group. The minimum PU split size may correspond to 8×8. The restricted partition group may correspond to one or more asymmetric motion partition (AMP) modes.

摘要： A method of improved texture-partition-dependent depth partition is disclosed. First, the available texture partitions for a collocated texture block are classified into two or more groups, and a set of candidate depth partitions is determined for each group. In one embodiment, at least one set of the candidate depth partitions contain more than one candidate depth partition and less than all candidate depth partitions. In another embodiment, the collocated texture blocks are classified into two groups, and one of the two groups includes the N×N texture partition and at least another texture partition. In yet another embodiment, the collocated texture blocks are classified into three groups or more. A current depth partition for the current depth block is then selected from a corresponding set of candidate depth partitions according to a corresponding group that a current texture partition associated with the collocated texture block belongs.

摘要： A method and apparatus for deriving inter-view candidate for a block in a picture for three-dimensional video coding are disclosed. Embodiments of the present invention derive the inter-view candidate from an inter-view collocated block in an inter-view picture corresponding to the current block of the current picture, wherein the inter-view picture is an inter-view reference picture and wherein the inter-view reference picture is in a reference picture list of the current block. The derived inter-view candidate is then used for encoding or decoding of the current motion vector or disparity vector of the current block. One aspect of the invention addresses re-use of the motion information of the inter-view collocated block. Another aspect of the invention addresses constrains on the inter-view picture that can be used to derive the inter-view candidate.
