Abstract: An image decoding method according to the present disclosure comprises the steps of: obtaining intra prediction type related information for a current block from a bit stream; deriving the intra prediction type of the current block based on the intra prediction type-related information; obtaining intra prediction mode-related information for the current block from the bitstream; configuring a most probable mode (MPM) list including candidate intra prediction modes for the current block based on neighboring blocks of the current block; deriving the intra prediction mode of the current block based on the MPM list and the intra prediction mode-related information; and generating a predicted block of the current block based on the intra prediction type and the intra prediction mode, wherein when the intra prediction type indicates the particular intra prediction type, the MPM index is parsed from the bit stream without parsing of an MPM flag.

Abstract: Neighboring blocks of a current block include first blocks adjacent to one of a top side, an above left corner, and an above right corner of the current block and second blocks adjacent to one of a left side and a below left corner of the current block. Whether one or more of the first blocks and the current block are in a same coding tree unit (CTU) is determined. Based on the one or more of the first blocks and the current block being in the same CTU, a respective intra mode associated with each of the one or more of the first blocks is added into a most probable mode (MPM) list for the current block based on a sequence of conditions. A respective intra mode associated with each of the second blocks is added into the MPM list based on the sequence of conditions.

Abstract: Coded information of (i) a current block of a picture and (ii) a reconstructed area of the picture is received. A matching area of the current block in the reconstructed area of the picture is determined. A first corresponding position of the current block is determined inside the current block. The first corresponding position includes a first coordinate value on a first axis and a second coordinate value on a second axis relative to a first reference point on the current block. A corresponding block of the current block is determined in the matching area. The corresponding block includes a second corresponding position that has the first coordinate value on the first axis and the second coordinate value on the second axis relative to a second reference point on the matching area. An intra prediction mode of the current block is determined based on the corresponding block.

Abstract: In a method, coded information of a current block and neighboring blocks of the current block in a current picture is received from a coded video bitstream. A list of merge candidates of the current block is generated based on the neighboring blocks of the current block. The list of merge candidates of the current block is divided into a plurality of subgroups. Each of the plurality of subgroups includes one or more merge candidates. The one or more merge candidates are ordered within each subgroup by a respective template matching (TM) cost associated with each of the one or more merge candidates. The current block is reconstructed based on a merge candidate selected from the list of merge candidates of the current block.

Abstract: In a method, coded information of a current block in a current picture is received from a coded video bitstream. The current block is partitioned into a plurality of subblocks. A first flag included in the coded information is obtained, where the first flag indicates whether a cross-component linear model prediction (CCLM) is applied to the current block in which chroma samples of the current block are predicted based on reconstructed luma samples of the current block. In response to the first flag indicating that the CCLM is applied to the current block, respective prediction sample values for the chroma samples in each of the plurality of subblocks of the current block are determined based on the CCLM. The current block is further reconstructed based on the respective prediction sample values for the chroma samples in each of the plurality of subblocks of the current block.

Abstract: A vision transformer includes L layers, and H attention heads in each layer. An h? of the attention heads include an attention mask added before a Softmax operation, and an h of the attention heads include unmasked attention heads in which H=h?+h. Each attention mask multiplies a Query vector and a Key vector for form element-wise products. At least one attention mask is a hard mask that selects closest neighbors of a patch and ignores patches further away than the closest neighbors of the patch. Alternatively, at least one attention mask includes a soft mask that multiplies weights of closest neighbors of a patch by a magnification factor and passes weights of patches that are further away than the closest neighbors of the patch. A learnable bias ? may be added to diagonal elements of the at least one attention map.

Abstract: One or more intra mode predictors of a current block are determined, where the one or more intra mode predictors are derived based on the neighboring samples of the current block via either a decoder side intra mode derivation (DIMD) or a template-based intra mode derivation (TIMD). Whether a position dependent intra prediction combination (PDPC) is to be applied is determined based on the one or more intra mode predictors. In response to the determining that the PDPC is to be applied, a fusion process is performed on the one or more intra mode predictors to combine the one or more intra mode predictors into a single intra mode predictor. The PDPC is applied based on the single intra mode predictor to generate a modified predictor of the current block. The current block is reconstructed based on the modified predictor generated by the PDPC.

Abstract: Coded information of a coding unit (CU) is received. The CU is partitioned into a first partition and a second partition based on a partition index. The partition index indicates a geometric partition mode (GPM) in which the CU is partitioned into the first partition and the second partition by a straight partition line. Based on a location of the straight partition line in the CU, (i) whether a first prediction mode of the first partition of the CU is one of an intra mode and an inter mode and (ii) whether a second prediction mode of the second partition of the CU is one of the intra mode and the inter mode are determined. The first partition of the CU is reconstructed based on the determined first prediction mode and the second partition of the CU is reconstructed based on the determined second prediction mode.

Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for non-linear breathing entrainment. As described herein, “breathing entrainment” refers to guiding a user's breath or breathing. According to an aspect, an initial breathing period and a final breathing period are selected. Based on the initial and final breathing periods, a non-linear breath rate per minute sequence is determined. A guiding stimulus is output and aligned with the non-linear breath rate per minute sequence. The guiding stimulus is non-linearly altered with the non-linear breath rate per minute sequence to align with the final breathing period over an interval of time. The non-linear alterations of the guiding stimulus vary based on an amount of time the guiding stimulus has been output.

Abstract: According to an aspect of the disclosure, a method of video decoding performed in a video decoder is provided. In the method, coded information of a current block in a current picture of a video is received from a coded video bitstream. The coded information indicates that the current block is an intra block copy (IBC) block. An intra prediction mode is derived for a subblock of the current block based on a reference subblock in a reference block. The reference subblock corresponds to the subblock of the current block, and the reference block is referenced by a block vector of the IBC block. The intra prediction mode for the subblock of the current block is further stored. A neighboring block of the current block is determined as an IBC block. A most probable mode (MPM) list is constructed for the neighboring block using the stored intra prediction mode.
