Description

technical field

[0001] The present invention relates to the field of signal processing and communication, in particular, to an area-based variable-resolution video coding method and an area-based video decoding method with variable resolution. Background technique

[0002] An important purpose of video coding is to compress the video signal to reduce the data volume of the video signal, thereby saving the storage space and transmission bandwidth of the video signal. On the one hand, the original video signal has a huge amount of data, which is the necessity of video coding and compression; on the other hand, there is a large amount of redundant information in the original video signal, which is the possibility of video coding and compression. These redundant information can be divided into spatial redundant information, temporal redundant information, data redundant information and visual redundant information. Among them, the first three kinds of redundant information only...
