Fast Playback Technique of Key Sequence Diagram based on Mixed Gauss Background Modeling and Super Compression

摘要

With the wide use of high speed cameras, the use of high frame frequency images and fast playback has become an important way to study the key events. In view of the problem of key frame retrieval and recognition and large capacity data remote transmission in fast playback, this paper proposes a technology of using Gauss background modeling and image super compression to achieve the fast playback reality of moving objects. Firstly, the imaging characteristics and background environmental characteristics of moving targets are analyzed, the steps of online modeling of mixed Gauss background are designed, and the implementation process and typical parameters are given. According to the target motion process, a playback script is customized, and the data volume and communication bandwidth of the high speed camera are calculated, a super compression ratio compression model based on transmission time, bandwidth and data volume is established. Combined with the method of application implementation, the modular block diagram and technical flow of replay processing are designed, and the basic relationship between the input and output parameters is clarified. The actual image sequence shows that in a typical target, equipment and network environment, using this technology can automatically identify key segment image sequences, realize image transmission and playback section can accurately judge the reality, for key events and provide effective technical support.
