摘要：With the rapid development of multimedia technologies, users can easily generate and share multiple videos through the Internet. Similarly, numerous illegal and useless near-duplicate videos generated through simple reformatting, transformation, and editing appear on the web. These near-duplicate videos inconvenience users when they are surfing the Internet and are considered a copyright infringement. Robust video hashing, which is also called video fingerprinting, does not require access to the video contents at the time of creation and can be used to detect existing contents. In general, a robust video hash is a short digest extracted from a video; however, it is robust to content-preserving attacks such as noise, logo addition, and contrast change. That is, similar to a human fingerprint that identifies a specific person, video hashing can classify video contents by extracting and comparing short digests. As such, video hashing is a feasible means to detect near-duplicate videos.
