Abstract: This disclosure provides an image encoding method and apparatus and an image decoding method and apparatus. For a to-be-encoded image in a to-be-encoded video sequence, a reference image may be selected from at least one knowledge-base image in a knowledge-base image set. In addition, bitstream data of the to-be-encoded image includes identification information used to identify the reference image of the to-be-encoded image.

Abstract: A picture encoding/decoding method and a related apparatus are provided. The picture decoding method includes obtaining a current picture; selecting, from a knowledge base, K reference pictures of the current picture, where at least one picture in the knowledge base does not belong to a random access segment in which the current picture is located and wherein K is an integer greater than or equal to 1; and decoding the current picture according to the K reference pictures.
