Abstract

The embodiment of the invention provides a video compression method, electronic equipment and a computer readable storage medium, and belongs to the technical field of digital image processing, and the method comprises the steps: reading a to-be-compressed video into a plurality of ordered video frames, carrying out the conversion and macro block division of each video frame, obtaining a plurality of to-be-processed frames, dividing multiple frames to be processed into multiple image groups, determining a reference frame from each image group, estimating a motion vector between the reference frame and each remaining frame to be processed by adopting a motion estimation algorithm by taking a macro block as a motion unit for each image group, encoding each motion vector to obtain multiple bit streams, encoding the reference frames according to the ratio of the pixel values, and obtaining the first code table of the reference frames and the first compressed file, converting the change between the images in the video into the motion vector, and encoding the motion vector and the reference frames, so that the video quality of the compressed file can be improved, and the size of the compressed file is reduced.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a video compression method, electronic equipment and a computer-readable storage medium. Background technique [0002] Video processing is a special case of digital image processing where the processed signal is a video file or video stream. Video processing is widely used in televisions, digital versatile discs (DVDs), and video players. In the case of long-distance processing, digital video signals can still maintain a very low bit error rate, but compared with analog video, digital video transmission requires higher transmission bandwidth and larger storage capacity. Therefore, video compression is usually used to reduce the amount of transmitted data. [0003] A digital-to-analog video sequence can contain up to 165mbps of data. In order to reduce the media overhead of distributing these sequences, video compression methods are adopted to: reduce color nuances in ima...
