Abstract

The invention discloses a video compression method, a video decompression method, an intelligent terminal and a storage medium. The video compression method comprises the following steps: acquiring a picture group of a video, and acquiring a forward frame and a backward frame of a B-frame original frame according to the picture group; obtaining the original frame of the B frame, performing motion compensation on the original frame of the B frame through a motion compensation network, and reconstructing the B frame; encoding the forward frame and the backward frame; and coding the reconstructed B frame according to the coded forward frame and the coded backward frame. The video decompression method comprises the following steps: acquiring a coded and compressed picture group in a video, the picture group comprising a coded B frame and a forward frame and a backward frame of the B frame; decoding the forward frame and the backward frame; and decoding the frame B according to the decoded forward frame and the backward frame. According to the invention, the coding and decoding effects of the B frame can be improved.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a video compression method, a video decompression method, an intelligent terminal and a storage medium. Background technique [0002] B-frame is also called bidirectional predictive frame. When encoding and decoding, forward frame and backward frame are required. It is the part with the highest compression rate in video compression, which can effectively reduce the encoding bit rate of video. When compressing a frame into a B frame, it compresses this frame according to the difference between the data of the adjacent previous frame, this frame, and the next frame, that is, only records the difference between this frame and the preceding and following frames. Only by using video compression can the high compression of 200:1 be achieved. Generally, I frames have the lowest compression efficiency, P frames have higher compression efficiency, and B frames have the h...
