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: A method, an image processing apparatus, and a system for generating a road image by using two-dimensional map data are proposed. The method includes receiving, by an image processing apparatus, an input of the map data of a specific area, extracting, by the image processing apparatus, road geometry information and road attribute information of a road from the map data, determining, by the image processing apparatus, road object standard information matched with the road attribute information for at least one road element of the road, generating, by the image processing device, style information for the at least one road element on a basis of at least one of the road attribute information and the road object standard information, and applying, by the image processing apparatus, the style information to the road geometry information to generate a basic road image including the road and the at least one road element.

Abstract: The present invention relates to a method and apparatus for encoding a displacement video using image tiling. A method for encoding multi-dimensional data according to an embodiment of the present disclosure may comprise: converting the multi-dimensional data into one or more frames with two-dimensional characteristics; generating one or more frame groups by grouping the one or more frames with pre-configured number units; reconstructing frames belonging to each frame group into a tiled frame; and generating a bitstream by encoding the tiled frame. Here, the tiled frame may be constructed with one or more blocks, and each block may be constructed by rearranging pixels existing at the same location in the frames.

Abstract: Disclosed herein are a garbage collection method and apparatus. The garbage collection method includes when an area dynamically allocated through a malloc( ) function or a new operator of a standard C library is deallocated through a free( ) function or a delete operator, inserting the deallocated area into a quarantine list, recording a base address and an end address of each of areas inserted into the quarantine list in a CSR_quarantined_chunks register, finding a physical address of a memory page used by a processor and searching data in the memory page for a value included in a quarantined area of the CSR_quarantined_chunks register, when a value included in the quarantined area is not present, setting a state flag bit of the register to 0, and deleting an area which the state flag bit is 0 from the quarantine list, and inserting the area into a free list.

Abstract: Disclosed is a mechanochromic array patch that implements, as a color change, a strain applied to a skin surface due to musculoskeletal movement. The mechanochromic array patch may include stretchable mechanochromic color-changing parts, a polymer connection part that connects the mechanochromic color-changing parts, and a water-insoluble support part. The polymer connection part may have a higher elastic modulus compared to the mechanochromic color-changing parts.
