Embodiment Construction

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work all belong to the protection scope of the present invention.

[0044]It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, in the p...

Abstract

The invention discloses a digital video interframe tampering detection method and system. The method comprises the steps of obtaining a to-be-detected digital video; converting the to-be-detected digital video into a video frame sequence sorted according to time; obtaining a difference matrix sequence sorted according to time; calculating the similarity between every two adjacent or spaced difference matrixes in the difference matrix sequence, obtaining an inter-frame similarity / time scatter diagram of the to-be-detected digital video according to all the similarities, and judging whether thedigital video has inter-frame tampering or not. The motion target action in the digital video which is not tampered is continuous; therefore, the inter-frame similarity / time scatter diagram between the adjacent or spaced difference matrixes should be smooth, whether the digital video has inter-frame tampering or not can be directly judged according to the inter-frame similarity / time scatter diagram, and a more efficient and accurate feasible scheme is provided for digital video tampering inter-frame detection.

Description

technical field [0001] The invention relates to the technical field of video detection, in particular to a method and system for detecting tampering between digital video frames. Background technique [0002] At present, digital video is widely used in various fields of society, and digital video has become a powerful way of information dissemination. With the rapid development of computer software application technology, various video editing software emerges in an endless stream, and video tampering operations become more and more foolish, so that people without any professional knowledge can use digital video editing software according to the operation tutorial. The video is tampered with at will. Some purposeful tampering libraries are used in aspects such as accident identification forensics, self-media-oriented publicity, and effective sample selection for big data calculations. Malicious tampering often brings some serious consequences, undermining judicial justice,...
