With recent technological advancement, a huge number of videos are created every day, and they are playing more and more important role in many application areas, such as communication, entertainment, social media, education, medicine, and surveillance. In many cases, videos contain significant information, whose authenticity is crucial. Unfortunately, forged videos can be easily created thanks to many digital image/video editing tools that are readily available for common people to manipulate images/videos. This project will develop some tools to detect forged videos.
The aim of this project is to develop deep learning-based video forgery detection methods that can identify forged videos and explain how the videos are forged. Explainable deep learning architectures are designed and tested for video forgery detection. Hierarchical methods are investigated, which involve extracting features from pixels, blocks, images, to videos levels and building links between the features and different types of forgery attacks. Visual dictionaries will also be explored for enhancing explanation.
Keywords: Video forgery detection, Explainable deep learning.
