VERFAHREN UND VORRICHTUNG ZUR DECODIERUNG BASIEREND AUF VORLAGENABGLEICH

摘要

The present invention discloses a decoding method based on template matching, including: obtaining a prediction direction identifier and encoded data of a current picture block; when a value of the prediction direction identifier indicates that the encoded data of the current picture block is obtained by performing bidirectional prediction on the current picture block based on a first motion information list of the current picture block and a second motion information list of the current picture block, determining the first motion information list of the current picture block and the second motion information list of the current picture block; determining first motion information based on the first motion information list; determining second motion information based on the second motion information list; and obtaining a reconstructed picture block of the current picture block based on the first motion information, the second motion information, and the encoded data of the current picture block. By using the solution provided in the present invention, decoding performance can be improved and computational complexity of decoding can be reduced.
