Reversible Data Hiding in Encrypted Image
TL;DR: This work proposes a novel reversible data hiding scheme for encrypted image, where the additional data can be embedded into the image by modifying a small proportion of encrypted data.
Journal ArticleDOI
Separable Reversible Data Hiding in Encrypted Image
TL;DR: This work proposes a novel scheme for separable reversible data hiding in encrypted images by exploiting the spatial correlation in natural image when the amount of additional data is not too large.
Journal ArticleDOI
Efficient Steganographic Embedding by Exploiting Modification Direction
Xinpeng Zhang,Shuozhong Wang +1 more
TL;DR: A novel method of steganographic embedding in digital images is described, in which each secret digit in a (2n+1)-ary notational system is carried by n cover pixels and, at most, only one pixel is increased or decreased by 1.
Journal ArticleDOI
Reversible Data Hiding: Advances in the Past Two Decades
TL;DR: In this paper, the various RDH algorithms and researches have been classified into the following six categories: 1) RDH into image spatial domain; 2) RD h into image compressed domain (e.g., JPEG); 3) RDh suitable for image semi-fragile authentication; 4)RDH with image contrast enhancement; 5) RD H into encrypted images, which is expected to have wide application in the cloud computation; and 6) RDD into video and into audio.
Journal ArticleDOI
An Effective CU Size Decision Method for HEVC Encoders
TL;DR: A fast CU size decision algorithm for HM that can significantly reduce computational complexity while maintaining almost the same RD performance as the original HEVC encoder is proposed.
