摘要： The present invention relates to a method of intra-predicting a block of a video picture according to a first intra-prediction mode using a first geometry transform identified by a first geometry transform type. The method determines (510) whether at least one neighboring block is predicted according to a second intra-prediction mode using a second geometry transform identified by a second geometry transform type and, if at least one neighboring block is predicted according to the second intra-prediction mode, the first geometry transform type is inferred (520) from said second geometry transform type.

摘要： The present application relates to intra predicting a chroma block of a video picture into a bitstream of encoded video picture data. A first predictor of the chroma block is derived based on a first non-linear-model based mode. If deriving a chroma predictor based on a linear-model based mode is disabled, a second predictor of the chroma block is derived based on a second non-linear-model based mode and a final predictor of the chroma block is determined by blending the first and second predictors.

摘要： The present application relates to bi-directional motion-compensated based predicting method of a block of a video picture. Two reference blocks in reference pictures in two distinct lists of reference pictures are determined for motion-compensation. The method determines if samples of a reference block is outside boundaries of a reference picture and in that case, determines a non-out-of-bound rectangular zone comprising at least one sample within said reference picture's boundaries and replaces said at least one sample that is outside the non-out-of-bound rectangular zone by corresponding samples of the other reference block which are within the other reference picture' boundaries.

摘要： The present application relates encoding/decoding a video picture into a bitstream of encoded video picture data comprising temporal predicting a video picture block by obtaining a temporal predicted block based on at least one reference block of at least one reference picture pointed to by at least one motion vector associated with the video picture block, wherein if the temporal prediction of the video picture block is based on a single reference block of a reference, then the method further comprises:
- padding (402) a padding region (SZ) of the reference block based on a motion vector derived from a nearest subblock of the video picture block inside the video picture; and
- determining a size (M) of the padding region (SZ) based on said motion vector.-

摘要： A method of deriving a Decoder-side Intra Mode Derivation, DIMD, predictor for respective samples of a coding unit, CU, of a picture is described. The method comprises splitting a template area adjacent to the CU into a plurality of template area regions, separately selecting no, one or more Intra Prediction Modes, IPMs, in each template area region, wherein the selection involves a selection out of the separately determined IPMs for the entire CU or for one or more regions of the CU, determining blending weights using the selected IPMs, and generating the DIMD predictor by blending at least the selected IPMs using the determined blending weights.

摘要： A method of determining filter characteristics of a filter for filtering respective samples of a template area adjacent to a coding unit, CU, of a picture so as to obtain from the template area respective Intra Prediction Modes, IPMs, for deriving Decoder-side Intra Mode Derivation, DIMD, predictor for respective samples of the CU is described. The method includes determining a size and/or a position of a filtering window of the filter dependent on one or more characteristics of the CU and/or the template area, or from information data associated with the picture.
