Abstract
AbstractWith the easy availability and operability of video editing tools, any video could be edited in short span of time. Sometimes, these modifications change the actual meaning of targeted video. Hence, before making any judgment and opinion about such multimedia contents, it is necessary to verify their genuineness. A video can be tampered by various different attempts. Each different attempt derives a new type of forgery in videos. Among various types of attack on video, frame duplication is a common type of attack. Frames are duplicated and pasted into same video in order to either hide or add false information. We propose Sub Blocked based features to detect frame duplication. The experimental results show higher accuracy that not only detects but also localize duplicated frames as well.KeywordsFrame duplicationImage forensicSub-blocking methodVideo forgeryCorrelation
