Abstract
A prediction value determination method and a decoder are provided. The method is for a decoder and includes the following. A bitstream is parsed to obtain a decoding parameter of a current block. A first template of the current block is obtained when the decoding parameter indicates that the current block uses a rotate template mode, where the first template contains a neighbouring reconstructed sample of the current block. A reference region of the current block is determined. In the reference region, a matching template of the first template is determined according to a reference template processing parameter, where the reference template processing parameter is a parameter contained in the decoding parameter and used to construct the matching template. A matching block of the current block is determined according to the matching template. A prediction value of the current block is determined according to the matching block.
