Patent number: 11265555Abstract: Disclosed are a method and apparatus for improving the accuracy of intra-prediction in order to improve encoding and decoding efficiency. The video decoding method may improve the prediction efficiency for the current pixel to be predicted by referring to the degree of variation in surrounding pixels, to thereby effectively decode the bit stream with improved encoding efficiency. In addition, an additional prediction candidate is used to achieve improved accuracy of intra-prediction, and the thus-improved accuracy of intra-prediction may reduce residual components and improve encoding efficiency. Further, an improved planar mode is utilized to achieve improved intra-prediction.Type: GrantFiled: June 12, 2020Date of Patent: March 1, 2022Assignee: INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITYInventors: Je Chang Jeong, Ki Baek Kim, Won Jin Lee, Hye Jin Shin, Jong Sang Yoo, Jang Hyeok Yun, Kyung Jun Lee, Jae Hun Kim, Sang Gu Lee
