A Review on Anaglyph 3D Image and Video Watermarking

Abstract

Thanks to the rapid growth of internet and the advanced development of 3D technology, 3D images and videos are proliferated over the networks. However, this causes several insecurity problems, and protecting this type of media has become a main challenge for many researchers. 3D watermarking is considered as an efficient solution for 3D data protection. In fact, it consists in embedding a secret key into a 3D content to protect it and in trying to extract it after any attack applied on marked 3D data. Anaglyph is the most popular and economical method among different 3D visualization methods. For this reason, it has become used for many 3D applications. Hence, 3D anaglyph watermarking presents an important research area, and several techniques have been proposed in order to protect this type of media. In this survey paper, the existing anaglyph 3D images and videos watermarking techniques are discussed. This discussion shows that the anaglyph video watermarking field is still not mature and new techniques should be proposed to improve the invisibility/robustness trade-off. In addition, based on the study of anaglyph generation methods, it is concluded that signature can be embedded during the generation stage.
