Reversible data embedding using a difference expansion
TL;DR: The redundancy in digital images is explored to achieve very high embedding capacity, and keep the distortion low, in a novel reversible data-embedding method for digital images.
Journal ArticleDOI
Reversible data hiding
TL;DR: It is proved analytically and shown experimentally that the peak signal-to-noise ratio of the marked image generated by this method versus the original image is guaranteed to be above 48 dB, which is much higher than that of all reversible data hiding techniques reported in the literature.

Lifting scheme: a new philosophy in biorthogonal wavelet constructions
TL;DR: In this paper, a new construction of biorthogonal wavelets which does not use the Fourier transform is presented, which leads to a faster, fully in- plane implementation of the wavelet transform.
