Problems solved by technology

[0004] However, the massive, high-dimensional, and non-linear characteristics of digital video data have brought great challenges to the research of video tampering detection methods.
Although many scholars at home and abroad have carried out related research and proposed a variety of different tamper detection methods, these methods still have problems such as low detection accuracy, high complexity, and strong limitations, which are not consistent with practical application requirements. There is still a big gap

Abstract

The invention relates to a detection method for video foreground deletion and tampering. Firstly, by calculating the energy factor of the video to be tested and constructing the energy factor curve, the start and end positions of the tampered video sequence are accurately detected in the time domain; secondly, by adopting an adaptive parameter The visual background extraction algorithm is improved to extract the tampering traces of each frame in the tampered video sequence; finally, the final detection result is obtained by combining the detection results of time domain and space domain. The present invention can realize the effective detection of foreground deletion and tampering in the video, and has the characteristics of short detection time, high detection accuracy, strong robustness, etc., and can effectively resist the influence of disturbances such as leaves, vegetation, and water waves in the video. Therefore, it provides an effective detection method for video area tampering and forensics.

Description

technical field [0001] The invention relates to the technical fields of the Internet and multimedia, in particular to a method for detecting deletion and tampering of a video foreground. Background technique [0002] With the vigorous development of the Internet and multimedia technology and the wide application of digital video, the authenticity of digital video content is becoming more and more serious. Many powerful video processing software are emerging, making it easy for non-professionals to use tools to process video content. Modify to achieve the effect of real ones. The content and meaning of tampered videos usually change. If these videos are used illegally, it may undermine judicial justice and even affect social stability. Therefore, it is increasingly urgent to determine the authenticity of the source and content of digital video, and digital video forensics has become one of the most important research topics in the field of information security. [0003] Del...
