Faced with drawbacks of JPEG 2000 lossless coding in network application as far as manipulation flexibility is concerned, this paper proposes a differential approach of implementa...
We present an efficient JPEG2000-based image authentication scheme, which is robust to JPEG compression and other allowed signal processing operations. Positive wavelet-based wate...
This paper investigates the robustness of the wavelet transform, implemented by means of the Lifting Scheme (LS), with respect to numerical errors in the representation and calcul...
Recently, among various data hiding techniques, a new subset, lossless data hiding, has received increasing interest. Most of the existing lossless data hiding algorithms are, howe...

In this paper, we propose a novel compression scheme for medical images with extended bit depth. Our scheme efficiently utilizes the VOI (value of interest) settings of the medica...
