Video Forensic

Video forensics
  Video forensics is an investigation technique for detecting manipulated(forged) video, and is a key technology for solving various image/video related legal problems.


Video forgery
  There are various methods for video forgery.
Video Forgery occurs in a variable ways without visible clues. We detect the forgery of the video by detecting the features of the forged video with some specific models like video coding patterns, frequency domain parameters and detecting whether the video has been compressed only once or not.



Detection of Frame Deletion in HEVC Compressed Domain
  We perform forged video classification with machine learning techniques using the features extracted from the verification video.
There is traditionally a forged video classification technique through machine learning. Recently, we have used forged video classification techniques using deep learning techniques which are useful in various fields.
