Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

Abstract: Disclosed herein are an apparatus for encoding and decoding a feature map and a method using the apparatus. The feature map encoding apparatus include a processor for acquiring feature map information corresponding to a feature map, reconstructing the feature map based on the feature map information, and generating an encoded feature map by converting each feature value corresponding to the reconstructed feature map from a real number into an integer, and a memory for storing the feature map information.

Abstract: Disclosed therein are a method, an apparatus, and a storage medium for image encoding/decoding. Templating matching is used for prediction for a target block. Prediction information to be applied to encoding of the target block is determined, and prediction for the target block that uses the determined prediction information is performed. The prediction information includes a list and multiple candidates in the list. When the multiple candidates in the list are configured, template matching between blocks may be used. A candidate selected from among multiple candidates configured using template matching is used for prediction for the target block.

Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. Encoding and decoding of a target block are performed using intra-prediction. The intra-prediction is intra-prediction that uses bidirectional intra-prediction and a remaining mode. In bidirectional intra-prediction, a prediction value for a target pixel in the target block is determined based on reference pixels in two directions of bidirectional intra-prediction. In intra-prediction using a remaining mode, the remaining mode indicates remaining intra-prediction modes other than MPMs present in an MPM list.
