摘要： A method of illumination compensation for three-dimensional or multi-view encoding and decoding. The method incorporates an illumination compensation flag only if the illumination compensation is enabled and the current coding unit is processed by one 2N×2N prediction unit. The illumination compensation is applied to the current coding unit according to the illumination compensation flag. The illumination compensation flag is incorporated when the current coding unit is coded in Merge mode without checking whether a current reference picture is an inter-view reference picture.

摘要： A method of MVP (motion vector prediction) for video coding with adaptive motion vector resolution is disclosed. According to the present invention, the MVP coding is applied to the current MV or the current MV is stored depending on the current MV resolution, the reference MV resolution, or both the current MV resolution and the reference MV resolution. In one embodiment, when the current MV resolution corresponds to integer pixel resolution, MVP coding is then applied to the current MV using a modified temporal MV as a motion vector predictor for the current MV, where the modified temporal MV is generated by right-shifting the temporal MV. In another embodiment, when the current MV resolution corresponds to integer pixel resolution, the current MV is left-shifted before it is stored in a memory.

摘要： A method for a three-dimensional encoding or decoding system incorporating sub-block based inter-view motion prediction is disclosed. The system utilizes motion or disparity parameters associated with reference sub-blocks in a reference picture of a reference view corresponding to the texture sub-PUs split from a current texture PU (prediction unit) to predict the motion or disparity parameters of the current texture PU. Candidate motion or disparity parameters for the current texture PU may comprise candidate motion or disparity parameters derived for all texture sub-PUs from splitting the current texture PU. The candidate motion or disparity parameters for the current texture PU can be used as a sub-block-based inter-view Merge candidate for the current texture PU in Merge mode. The sub-block-based inter-view Merge candidate can be inserted into a first position of a candidate list.

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 and apparatus for depth lookup table (DLT) signaling in a three-dimensional and multi-view coding system are disclosed. According to the present invention, if the pictures contain only texture data, no DLT information is incorporated in the picture parameter set (PPS) corresponding to the pictures. On the other hand, if the pictures contain depth data, the DLT associated with the pictures is determined. If a previous DLT required for predicting the DLT exists, the DLT will be predicted based on the previous DLT. Syntax related to the DLT is included in the PPS. Furthermore, first bit-depth information related to first depth samples of the DLT is also included in the PPS and the first bit-depth information is consistent with second bit-depth information signaled in a sequence level data for second depth samples of a sequence containing the pictures.

摘要： A method and apparatus for low-latency illumination compensation in a three-dimensional (3D) and multi-view coding system are disclosed. According to the present invention, the encoder determines whether to enable or disable the illumination compensation for the current picture or slice based on a condition related to statistic associated with a selected reference picture or slice respectively, or related to high-level coding information associated with the current picture or slice respectively. The high-level coding information associated with the current picture or slice excludes any information related to pixel values of the current picture or slice respectively. The illumination compensation is them applied according to the decision made by the encoder. A similar low-latency method is also applied for depth lookup table (DLT) based coding.

摘要： A method of three-dimensional video encoding or decoding that uses unified depth data access for VSP process and VSP-based merging candidate derivation is disclosed. When the coding tool corresponds to VSP process or VSP-based merging candidate, embodiments of the present invention fetch the same reference depth data in a reference view. A reference depth block in a reference view corresponding to the current texture CU is fetched using a derived DV (disparity vector). For the VSP process, first VSP data for a current PU (prediction unit) within the current CU is generated based on the reference depth block. For the VSP-based merging candidate derivation, second VSP data for a VSP-coded spatial neighboring PU associated with a VSP spatial merging candidates is generated also based on the reference depth block.

摘要： A method of deriving VSP (View Synthesis Prediction) Merge candidates with aligned inter-view reference pictures is disclosed. The method generates a second Disparity Vector (DV) using a scaled DV derived from Neighboring Block Disparity Vector (NBDV) of the current block. A method of deriving one or more inter-view DV Merge candidates with aligned DV and associated inter-view reference pictures is also disclosed. The inter-view reference picture pointed by the DV derived from Depth oriented NBDV (DoNBDV) is used as the reference picture and the DV derived from DoNBDV is used as the DV for inter-view DV Merge candidate. Furthermore, a method of deriving temporal DV for NBDV is disclosed, where if the temporal neighboring block has a DV existing, the DV is used as an available DV for the current CU only if the associated inter-view reference picture exists in the reference lists of the current CU.

摘要： A method for inter-color residual prediction using an improved scaling parameter coding is disclosed. In one embodiment, a scaling parameter is used for inter-color residual prediction between a first color component and a second color component. The scaling parameter is coded using context-based coding having the same number of context models as the longest binary code for the absolute values of the scaling parameter. For example, when the first scaling parameter is selected from a group consisting of 8, 4, 2, 1, 0, −1, −2 −4 and −8, the absolute values of the scaling parameter can be represented by binary codes with the longest binary code having 4 bits. The context-based coding for the absolute scaling parameter also uses 4 context models. In a second embodiment, the scaling parameter is coded using binary codes by assigning a shorter binary code to a larger non-zero scaling parameter.
