An overview of Advanced Optical Flow Techniques for Copy Move Video Forgery Detection

The establishment of digital media such as video, photographs, and audio throughout the web in recent years has expanded the opportunity to shape digital forgeries. The technique developed by hackers recently, by implementing duplication operation or copy-move on top of the list. The central idea is to hide from view or incorporate an object in a video frame to create a new frame or scene and the process is well known and exploited for suppressing an evidence from being discovered. This survey paper focuses on techniques that uses optical flow that could be the key strategy for calculating the movement of picture power, that may be attributed to the movement of objects contained by the scene.
