Abstract: Disclosed are a method and an apparatus for transmitting or receiving uplink feedback information in a communication system. An operation method of a terminal may comprise receiving downlink control information (DCI) from a base station, the DCI including resource allocation information of a physical downlink shared channel (PDSCH); receiving data #n from the base station through the PDSCH indicated by the DCI; generating a hybrid automatic repeat request (HARQ) codebook including an HARQ response bit #n for the data #n and an HARQ response bit #n−1 for data #n−1 received from the base station before the data #n; and transmitting the HARQ codebook to the base station. Therefore, the performance of the communication system can be improved.

Abstract: The present invention relates to an image encoding/decoding method and apparatus. The image decoding method according to the present invention may comprise reconstructing an intra prediction mode of a current block, determining a reference sample for intra prediction of the current block, and generating a prediction block of the current block by performing the intra prediction on the current block on the basis of the intra prediction mode and the reference sample. The determining of the reference sample or the intra prediction may be performed on the basis of a shape of the current block.

Abstract: Disclosed herein are an apparatus and method for user authentication based on multiple pieces of biometric information. The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives multiple pieces of biometric information from the client device of a user, generates the personal identifier of the user using a neural network and a Bloom filter algorithm, and checks the similarity between the personal identifier of the user and each of personal identifiers previously registered in a database, thereby authenticating the user.

Abstract: Disclosed herein are an apparatus and method for a multiplication operation based on an outer product. The apparatus may include first internal calculators, each of which generates an intermediate accumulation value by performing a Multiply-Accumulate (MAC) operation, second internal calculators, each of which generates a chunking accumulation value using the intermediate accumulation value, and accumulation data transmission paths for enabling the output of any one of the first internal calculators to be input to any one of the second internal calculators.

Abstract: Disclosed herein are an immersive video decoding method and an immersive video encoding method. The immersive video decoding method includes partitioning a current picture into multiple main blocks, determining whether each main block is to be partitioned into multiple sub-blocks, and when it is determined that each main block is to be partitioned into multiple sub-blocks, determining a partitioning type of the corresponding main block. Here, the corresponding main block may be partitioned into four or two sub-blocks depending on the partitioning type. When the corresponding main block is partitioned into multiple sub-blocks, whether depth information is to be updated for each of the sub-blocks generated by partitioning the main block may be determined.

Abstract: Disclosed are region-based image encoding/decoding method and apparatus. The method of decoding an image includes: determining a projection format of a 360-degree video image; determining, on the basis of the determined projection format, a spatial correlation degree between a current block and a neighboring block; and determining, on the basis of the determined spatial correlation degree, a candidate block for predicting the current block.

Abstract: Provided are an image encoding method and device. When carrying out image encoding for a block within a slice, at least one block in a restored block of the slice is set as a reference block. When this is done, the encoding parameters of the reference block are distinguished, and the block to be encoded is encoded adaptively based on the encoding parameters.
