Method for intra prediction of video sequences
A recently granted patent (Publication Number: US11930187B2) discloses a method and apparatus for performing intra prediction of a current block of a picture in a video sequence. The method involves receiving video data, encoding pictures into a coded video sequence, and setting flags to determine the intra prediction mode. The flags indicate whether the mode is directional or DIMD, and based on these flags, the method selects an intra prediction mode from an allowed list and performs the intra prediction of the current block accordingly. Additionally, the method includes performing DIMD to determine the intra prediction mode and inserting the determined mode into the AIPM list for future use.
The patent also covers an apparatus for implementing the method, comprising at least one memory and processor configured to execute the computer program code. The apparatus receives video data, encodes pictures, and sets flags to determine the intra prediction mode. It further includes code for performing DIMD, inserting the determined mode into the AIPM list, and conducting intra prediction for chroma components. The apparatus is designed to handle both directional and non-directional modes, ensuring efficient intra prediction for various types of video sequences. Overall, the patent aims to enhance the encoding process by optimizing the selection and utilization of intra prediction modes, ultimately improving the quality and compression efficiency of video sequences.
