Patent number: 11438623Abstract: A coding tool is provided to improve the compression performance of inter prediction and is used at the encoder/decoder side to adjust the correction of a motion vector based on a high level syntax. In addition, a method is provided for simply performing an integer sample search step of searching for an integer offset and a fractional sample refinement step of searching for a sub-pixel offset in relation to motion vector refinement among coding tools.Type: GrantFiled: July 8, 2020Date of Patent: September 6, 2022Assignees: Hyundai Motor Company, Kia Motors Corporation, Ehwa University-Industry Collaboration FoundationInventors: Je Won Kang, Sang Hyo Park, Seung Wook Park, Wha Pyeong Lim

Patent number: 11432002Abstract: A video decoding apparatus is provided for decoding pictures using inter-prediction. The video decoding apparatus includes a predictor that generates affine prediction samples for respective subblocks in a target block in a current picture to be decoded by performing affine motion prediction on a subblock-by-subblock basis using control point motion vectors which respectively correspond to corners of the target block. The predictor also modifies sample values of the affine prediction samples by executing a first coding tool, the first coding tool compensating for motion according to sample positions in each of the subblocks using the control point motion vectors.Type: GrantFiled: July 8, 2020Date of Patent: August 30, 2022Assignees: Hyundai Motor Company, Kia Motors Corporation, Ehwa University-Industry Collaboration FoundationInventors: Je Won Kang, Seung Wook Park, Wha Pyeong Lim

Patent number: 9745605Abstract: The present invention relates to a transformant which is transformed to express Baeyer-Villiger monooxygenase (BVMO), a method for producing C5-C14 medium-chain ?-hydroxy fatty acids, ?,?-dicarboxylic acids, ?-amino fatty acids, or alcohols from C16-C20 long-chain fatty acids by biotransformation using the transformant, a method for producing a fatty acid derivative having an ester group which is introduced into the chain thereof from keto fatty acid using the BVMO, and novel ?-hydroxy fatty acids which are prepared by the method. Degradation products such as C5 to C14 ?-hydroxy fatty acids, ?,?-dicarboxylic acids, ?-amino fatty acids, alcohols can be produced in a large amount from C16 to C20 long-chain fatty acids contained in a medium by biotransformation using a transformant capable of expressing BVMO of the present invention. Therefore, it can be widely used to produce ?-hydroxy fatty acids, ?,?-dicarboxylic acids, ?-amino fatty acids or alcohols in a more safe and economic manner.Type: GrantFiled: April 5, 2013Date of Patent: August 29, 2017Assignee: EHWA UNIVERSITY-INDUSTRY COLLABORATIONInventors: Jin Byung Park, Ji Won Song, Eun Yeong Jeon
