Patent number: 11363276Abstract: Embodiments of the present disclosure provide an intra-frame prediction method and apparatus, and a non-transitory computer-readable storage medium. In the method, pixel main directions of reference coded blocks that spatially neighbor a target to-be-coded block are determined. For each of the pixel main directions, a search is performed for an intra-frame prediction direction that is within a set distance value of the respective pixel main direction. Candidate intra-frame prediction directions are formed at least according to the intra-frame prediction directions. Prediction and coding are performed on the target to-be-coded block according to the candidate intra-frame prediction directions. Further, a target intra-frame prediction direction in the candidate intra-frame prediction directions is determined according to results of the prediction and coding on the target to-be-coded block according to the candidate intra-frame prediction directions.Type: GrantFiled: October 2, 2019Date of Patent: June 14, 2022Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Sixin Lin, Ximing Cheng

Publication number: 20190222842Abstract: A coding unit (CU) depth determining method and apparatus are provided. The method includes determining a residual coefficient of a current optimal mode of a to-be-processed CU; and respectively obtaining, when the residual coefficient is not 0, coding information features of the to-be-processed CU corresponding to a specific frame type and coding information features of a neighboring coding tree unit (CTU) corresponding to the specific frame type of a CTU in which the to-be-processed CU is located, to form prediction feature vector samples. The method also includes inputting the prediction feature vector samples to a pre-trained predictive model corresponding to the specific frame type, to obtain a prediction result. The prediction result indicates whether depth division needs to be performed on the to-be-processed CU.Type: ApplicationFiled: March 27, 2019Publication date: July 18, 2019Inventors: Hongshun ZHANG, Sixin LIN, Ximing CHENG
