Original Abstract Submitted
This disclosure relates generally to video coding/decoding and particularly prediction using multiple scaling factors and multiple samples. One method includes receiving a video bitstream comprising a current block and a reference block, the reference block being used for predicting the current block by using a prediction function; receiving, from the video bitstream, a first syntax element indicating a manner for determining parameters of the prediction function; determining the parameters of the prediction function based on the manner; predicting a current sample in the current block based on the reference block using the prediction function; and reconstructing the current block based on the predicted current sample.
