Title: Image Copy Detection Based on Perceptual Hashing

Abstract: Nowadays, Image copy detection is an important task on Internet and social media platform, which can be effectively used to achieve image copyright protection and authentication. In this talk, we will focus on how to realize image copy detection with perceptual hashing technique. First, the concept of perceptual hashing and its differences with cryptographic hash function and semantic retrieval hashing are given. Then, representative methods of perceptual image hashing for copy detection are introduced detailedly, including traditional methods and deep learning-based methods. Finally, the summary and further research directions are discussed.
