Patent number: 11973952Abstract: A prediction unit (60) for an encoder (24) or decoder (44) implements matrix based intra prediction Input boundary samples for a current block are downsampled to obtain reduced boundary samples for matrix multiplication and/or linear interpolation, or both. In one embodiment, downsampling is performed in a manner that aligns the reduced boundary samples with an output of a matrix multiplication unit of the prediction unit. In other embodiments, downsampling is performed without averaging. The embodiments reduce the complexity of the prediction unit and the latency of the encoder (24) or decoder (44).Type: GrantFiled: June 12, 2020Date of Patent: April 30, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Zhi Zhang, Ruoyang Yu, Kenneth Andersson, Per Wennersten, Jacob Ström, Rickard Sjöberg

Patent number: 11943478Abstract: A method, decoder, and apparatus are provided. Responsive to a current block being a MIP predicted block, it is determined whether it has one or multiple transform blocks. A MIP weight matrix to be used to decode the current block is determined based on a MIP prediction mode. Responsive to the MIP predicted block having one transform block, the MIP predicted block is derived based on the MIP weight matrix and previously decoded elements in the bitstream. Responsive to the MIP predicted block having multiple transform blocks: deriving a first MIP predicted block is derived based on the MIP weight matrix and previously decoded elements in the bitstream and remaining MIP predicted blocks are derived based further on decoded elements in at least one decoded transform block of the current block. The MIP predicted block(s) are output for subsequent processing.Type: GrantFiled: September 17, 2020Date of Patent: March 26, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Zhi Zhang, Kenneth Andersson, Davood Saffar, Rickard Sjöberg, Jacob Ström, Ruoyang Yu

Publication number: 20240098256Abstract: An encoded video sequence including a plurality of images may be decoded. First and second adjacent blocks of an image of an encoded video sequence may be provided. A line of pixels including pixels of the first and second blocks may be defined extending across a boundary between the first and second blocks. A first reference value may be calculated based on a first pixel of the pixels from the first block. A second reference value may be calculated based on a second pixel of the pixels from the second block. Filtered pixel values for each pixel of the line of pixels between the first pixel and the second pixel may be calculated using interpolation based on the first and/or second reference values. Filtered blocks may be generated using the filtered pixel values, and a decoded video sequence may be generated based on the filtered blocks.Type: ApplicationFiled: November 30, 2023Publication date: March 21, 2024Inventors: Kenneth ANDERSSON, Jack ENHORN, Rickard SJÖBERG, Jacob STRÖM, Per WENNERSTEN
