Abstract

The invention belongs to the technical field of multimedia information security, and particularly relates to a video object removal tampering time-space domain positioning method based on deep learning, which comprises the following steps: S1, training a time domain positioning model and a space domain positioning model; S2, inputting a to-be-tested video into the time domain positioning model toobtain a tampered frame sequence; and S3, inputting the tampered frame sequence into the spatial domain positioning model to obtain a tampered area positioning result in the tampered frame. Accordingto the method, the tampered frames can be detected from the tampered video, and the tampered area can be positioned in each tampered frame.

Description

technical field [0001] The invention belongs to the technical field of multimedia information security, and in particular relates to a time-space domain positioning method for video object removal and tampering based on deep learning. Background technique [0002] In recent years, video surveillance has been seen everywhere as public and even private security equipment, but with the development of digital video and image processing technology, it has brought great challenges to the integrity and authenticity of video content. Once these videos are manipulated by criminals, it will have a huge impact on public security and judicial evidence collection. Usually, after these videos have been highly tampered with, people cannot tell the real from the fake with the naked eye. Therefore, how to ensure the authenticity and integrity of the video through the computer is very important. [0003] Digital video is composed of visual objects with a certain spatial structure and semant...
