Abstract: Encoding and decoding methods and apparatuses, which can fully utilize a spatial correlation in video information, thereby improving compression efficiency during encoding and decoding where the method includes determining, according to a total coding cost of a target image, a first processing order of multiple code blocks groups included in the target image, encoding a code blocks group of the multiple code blocks groups according to the first processing order, to generate a bitstream, and writing the first processing order to the bitstream. A first processing order of multiple code blocks groups included in a target image is determined according to a total coding cost of the target image, and the multiple code blocks groups are encoded and decoded according to the first processing order such that a spatial correlation in video information may be fully utilized, thereby improving compression efficiency during encoding and decoding.
