Abstract: A massage mechanism includes a connecting seat, a supporting seat assembly, upper massage arms, lower massage arms, a kneading shaft and a first driving assembly. The first driving assembly is used for driving the kneading shaft to rotate, such that a connecting member and a connecting shaft are driven to perform a reciprocating motion on each supporting seat assembly, and upper massage rolling wheels and lower massage rolling wheels are close to each other or away from each other, so as to achieve a shoulder clamping action. The two upper massage arms and the upper massage rolling wheels are driven to be close to each other or away from each other, and the two lower massage arms and the lower massage rolling wheels are close to each other or away from each other, so as to achieve a kneading action.

Abstract: Provided are an intra prediction method and apparatus, and a computer-readable storage medium. The method includes: acquiring a first reference sample set corresponding to the current processing block, wherein the first reference sample set includes at least one of a reference row adjacent to the current processing block and a reference column adjacent to the current processing block; selecting, based on a pre-set selection method, a second reference sample set from the first reference sample set, wherein the second reference sample set includes at least one reference sample in the reference row adjacent to the current processing block or the reference column adjacent to the current processing block; obtaining, based on the second reference sample set, a prediction value of the current processing block; and performing, based on the prediction value, intra prediction on the current processing block.

Abstract: The embodiments of the disclosure disclose a method for determining a prediction direction, a decoder and a computer storage medium. The method is implemented by a decoder. The method includes that: a Direct Mode (DM) in a chroma intra prediction mode of a block to be decoded is acquired (S101); and an index number of a prediction direction in a DM derived mode is determined based on an offset N and an index number M of a prediction direction in the DM to determine the DM derived mode (S102).
