Abstract: Disclosed is a method for video encoding and decoding using adaptive color transform on a residual signal. In particular, the maximum memory size required for adaptive color transform is limited by: controlling whether to allow color space conversion on a sequence level according to a syntax element indicating the maximum conversion size allowed for a sequence of pictures; or controlling whether to apply color space conversion on a block level according to the size of a coding block.

Abstract: Proposed are an on chip multi-core system and an optimizing method for PR resource selection in which management for allocating a plurality of partial regions (PRs) constituting a reconfigurable resource pool to a corresponding core of multiple cores and management for reconfiguring the inside of each PR can be separately performed, fragmentation can be minimized after the allocation of the PRs, and the reconfiguration time of an accelerator can be shortened. The on chip multi-core system includes a PR map, a core unit, a PR resource management processor, an inter PR routing controller, a bitstream memory, and an intra PR configuration controller.

Abstract: Disclosed is a method for signaling virtual boundary information and constraining an operation of an in-loop filter on a virtual boundary by using the signaled boundary information in order to prevent performance deterioration which may occur when applying the in-loop filter for a discontinuous boundary (or virtual boundary) depending on frame packing in an encoding/decoding of a 360-degree omnidirectional video.

Abstract: A method and a system for providing a roughness haptic sense of a virtual object by using space-time encoding are provided. The method for providing a roughness haptic sense of a virtual object may comprise the steps of: displaying virtual objects to a user; tracking the position of the user's hand; predicting a virtual object, which is most likely to collide with the hand, among the virtual objects; and when the hand touches a haptic sense providing device, controlling the haptic sense providing device on the basis of the surface roughness of the predicted virtual object to feed back a roughness haptic sense to the user.

Abstract: The present invention relates to: recombinant microorganisms expressing lipoxygenase; and recombinant microorganisms co-expressing lipoxygenase and Chlorella-derived decarboxylase. It was confirmed that when using lipoxygenase-based recombinant microorganisms according to the present invention as whole-cell biocatalysts, hydroxy fatty acids can be produced from unsaturated fatty acids. In addition, it was confirmed that when using the recombinant microorganisms co-expressing lipoxygenase and Chlorella-derived decarboxylase as whole-cell biocatalysts, secondary fatty alcohols can be produced from unsaturated fatty acids. Thus, the recombinant microorganisms constructed in the present invention can be used in various ways in the field of hydroxy fatty acid and secondary fatty alcohol production.

Abstract: Disclosed are a method and device for generating a three-dimensional (3D) model through RGB-D camera tracking. A 3D model generation method may comprise the steps of: identifying RGB images and depth images; determining an initial camera pose of an RGB-D camera for each original frame of the depth images and the RGB images; determining a final camera pose for each of the original frames by updating the initial camera pose by using differences between an original frame, transformed according to the initial camera pose, and remaining original frame among two consecutive original frames of the depth images and the RGB images; selecting key vertexes capable of covering all original vertexes among original vertexes; and generating a 3D model by using key-frames, corresponding to the key vertexes in the original frames of the depth images and the RGB images, and final camera poses corresponding to the key-frames.

Abstract: A method and apparatus for intra-prediction coding of video data are provided. The apparatus includes a decoder that is configured to decode, from a bitstream, a syntax element indicating an intra-prediction type of a current block of the video data, and an intra-predictor that is configured to generate a prediction block for the current block by selectively performing matrix based intra-prediction or regular intra-prediction based on the intra-prediction type of the current block indicated by the syntax element.
