| Abstract: | Abstract: Digital visual media forensics is an effective solution of the authentication of visual media. It does not need to insert any additional information in the acquisition process so that it could be used in a wide range of fields. This paper first introduces the origin and concept of digital visual media forensics; representative double compression detection and forgery detection algorithms are introduced in detail afterwards. On this basis, we discuss the relationships between different forensic algorithms and existing problems of visual media forensic techniques. Perspectives of the development of digital visual media forensics are put forward in the end. |
