The method of video decoding includes obtaining a first parameter based on a first neighbor block of a current block; obtaining a second parameter based on the first neighbor block and/or a second neighbor block of the current block; constructing an affine model using the first parameter and the second parameter; and obtaining a control point motion vector (CPMV) for the current block based on the affine model. The first neighbor block and the second neighbor block are obtained from a plurality of neighbor blocks to the current block based on at least one scanning area and at least one scanning distance. The first neighbor block and the second neighbor block are obtained by scanning the at least one scanning area at the at least one scanning distance.

摘要： Implementations of the disclosure provide a video processing method for performing intra prediction on a video block. The video processing method may include receiving reconstructed samples from a video frame in the bitstream including the video block. The video processing method may further include determining reference samples in neighboring video blocks of the video block according to a first slant line and a second slant line through a sample of the video block. The first slant line is along an interpolation direction and the second slant line is perpendicular to the first slant line. The video processing method may also include interpolating the sample of the video block based on the reference samples.

摘要： Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for video coding. In one method, a decoder receives a signaled flag that indicates whether a template-based intra mode derivation (TIMD) mode is applied on a current video block; and in response to determining that the TIMD mode is applied on the current video block based on the signaled flag, the decoder derives an intra prediction mode from the TIMD mode based on different reference lines in a reconstruction area of the current video block, where the reconstruction area comprises reconstructed neighboring blocks for the current video block.

摘要： Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for video decoding. In one method, a decoder identifies a floating-point division operation to be performed to derive parameters in decoder-side intra mode derivation (DIMD) mode or in template-based intra mode derivation (TIMD) mode; and the decoder obtains the parameters in the DIMD mode or the TIMD mode by replacing the floating-point division operation with integer additions and multiplications based on a look-up-table (LUT).
