Abstract

The invention discloses a video copy detection system based on a convolutional and recurrent neural network. The system includes five modules, which are a data set establishment module, a frame feature extraction module, a spatio-temporal feature training module, a loop network test module and a copy video matching module. The spatio-temporal feature training module also includes video editing module and loop network training module. The invention adopts a residual convolutional neural network to extract deeper frame-level feature representationto improve the detection accuracy and reduce thedetection recall effectively. A twin-loop neural network is used to fuse multiple frame-level features, and the spatio-temporal feature representation is generated by using the dynamic information between frames, so the spatio-temporal fusion between sequences is realized, and video matching takes less time and occupies less memory.

Description

technical field

[0001] The invention relates to a video copy detection system and method, in particular to a video copy detection system and method based on convolutional and cyclic neural networks. Background technique

[0002] With the development of network multimedia technology, network video data is increasing massively, and a large amount of video data is made public on the Internet. Internet users can search for different types of videos such as politics, entertainment, sports, etc. on Youtube or MetaCafe. Although online video allows Internet users to obtain the latest information from all over the world, there are also some potential risks. Pirates can easily steal or tamper with online original videos to earn illegal income. Therefore, copy detection technology based on video analysis is of great significance to network security and copyright protection.

[0003] In early video copyright protection tasks, watermarks or digital tags were inserted into video strea...
