Video compression coding and decoding method and device

Abstract

The invention discloses a video compression coding and decoding method based on video content analysis. The video compression coding and decoding method comprises the following steps of: establishing background models of videos in real time, and carrying out compressed coding on background videos according to the background models; detecting a foreground movement target, storing the relevant information of the foreground movement target, and carrying out compressed coding on foreground video data according to the detected foreground movement target; integrating the background video data and foreground video data subjected to compressed coding into new video files; and decoding the new video files, and playing the videos after integrating the background video data and foreground video data subjected to compressed coding. The video compression coding and decoding method is on the basis of a general coding and decoding manner, and the new video files are generated through separation and coding of the background and foreground video data. The video files greatly reduce the storage space and improve the compression ratio and the storage cycle of video equipment. Finally, the fluent playing of the videos can be realized through video encoding and data integration.

Description

Technical field [0001] The present invention relates to the field of video analysis, in particular to an efficient video compression coding and decoding method, which is a video compression method that separates the foreground and the background and separately encodes and stores them. Background technique [0002] With the continuous development of multimedia information technology, a large number of video information has emerged. As a comprehensive medium for expressing information, video data has become an important information carrier in our real life. With the increasing popularity of surveillance imaging equipment, massive amounts of video data have been generated, and video storage is a very important link in the application of video surveillance systems. Large amounts of video data usually need to be stored for a long time to provide services for the retrieval and playback of video recording materials in the future. [0003] The most common way to store video data is to si...

Problems solved by technology

[0006] Traditional compression technology only performs video compression based on the data correlation of the front and rear frames, and does not distinguish between monitoring background and dynamic target information. Improving the compression rate will sacrifice the image quality of the monitoring background and dynamic targets at the same time.
