    摘要： An intra prediction method, for video decoding, comprises the steps of (S1410) receiving information on prediction for a current block (600), (S310, S1420) deriving an intra prediction mode of the current block (600) based on the information on the prediction, and (S340, S1430) generating a predicted block of the current block based on the intra prediction mode, wherein the predicted block comprises predicted samples. The intra prediction mode is a vertical prediction mode. Among the predicted samples, a predicted sample (620) is derived by using a first reference sample (610) located along a vertical prediction direction with regard to a location of the predicted sample (620). The step of generating the predicted block includes filtering the predicted sample (620) when the predicted sample (620) is adjacent to a left boundary of the current block (600). The filtering the predicted sample (620) is performed based on a second reference sample (630) which is located outside of the current block (600), is located along a horizontal direction with regard to the location of the predicted sample (620) and is adjacent to the left boundary of the current block (600)

    摘要： The present invention relates to an intra prediction method for video decoding and video encoding. The intra prediction method for video decoding comprises steps of: (S310, S1420) deriving an intra prediction mode for a current block (700) and (S340, S1430) generating a predicted block which includes prediction samples by deriving a prediction sample (720) for the current block (700) based on a first reference sample (730). When the intra prediction mode is a horizontal prediction mode, the generating the predicted block includes filtering the prediction sample (720) which is one of prediction samples adjacent to a top boundary of the current block (700). The first reference sample (730) is located along a horizontal prediction direction with regard to a location of the prediction sample (720), wherein the first reference sample (730) is located outside of the current block (700) and is adjacent to a left boundary of the current block (700). The filtering the prediction sample (720) is performed based on a second reference sample (710) which is located along a vertical direction with regard to the location of the prediction sample (720), wherein the second reference sample (710) is located outside of the current block (700) and is adjacent to the top boundary of the current block (700).

    摘要： New intra angular prediction modes and methods for decoding are offered for providing greater accuracy when processing predictions of digital video data blocks. One new method considers predicting a current prediction sample by taking the linear interpolation of two previously reconstructed reference samples that lay along a common angular line. Another new method offers a method for making previously unavailable samples from a neighboring block available as reference samples when predicting a current prediction sample. Another new method considers a new combined intra prediction mode that utilizes a local mean to predict a current prediction sample. And a new decoding method offers to rearrange the order in which video data blocks are predicted based on the intra prediction mode used for predicting the video data blocks.

    摘要： A decoding apparatus for image decoding comprises a memory and at least one processor connected to the memory. The at least one processor is configured to receive information on a parallel merge level which represents a size of a parallel merging unit region and merge index information; obtain merge flag information which represents whether a merge mode is applied to a current block; derive spatial merging candidates for the current block based on the merge flag information indicating that the merge mode is applied to the current block; construct a merging candidate list including the spatial merging candidates for the current block; derive motion information of the current block based on one of the spatial merging candidates indicated by the merge index information in the merging candidate list; derive prediction samples of the current block based on the derived motion information; and generate a reconstructed picture based on the prediction samples. The size of the parallel merging unit region is derived based on the information on the parallel merge level. The current block belongs to the parallel merging unit region. The current block is related to a prediction unit, PU, and the PU is one of PUs partitioned from a coding unit, CU. The PU has a size smaller than the size of the parallel merging unit region and is located within the parallel merging unit region. The spatial merging candidates are identical to spatial merging candidates of a 2Nx2N PU which has a same size as the parallel merging unit region. The spatial merging candidates of the 2Nx2N PU which has the same size as the parallel merging unit region, are derived from a lower left corner neighboring block, a left neighboring block, an upper right corner neighboring block, an upper neighboring block and an upper left corner neighboring block of the parallel merging unit region. The information on the parallel merge level is received through a picture parameter set.
