Reversible Data Hiding (RDH) is the process of transferring secret data hidden inside cover media to recipient so can securely retrieve both and media. The RDH approach applied in this study field telemedicine, medical-secret conveyed privately via medical video. Morse code-based encryption technique tends encrypt by compression using Arithmetic coding technique. Discrete Shearlet transform (DS...

In J. T. Wilson’s doctoral dissertation, the author takes up the subject of free meets, that is, subsets S of a frame L whose meet V S is preserved by a designated class of frame homomorphisms out of L. Wilson proves that all subsets of L have free meets if and only if the dual frame law holds in L and the assembly NL is a boolean frame. In this paper it is shown that for algebraic frames L wit...

Abstract. Certain facts about frames and generalized frames (g- frames) are extended for the g-frames for Hilbert C*-modules. It is shown that g-frames for Hilbert C*-modules share several useful properties with those for Hilbert spaces. The paper also character- izes the operators which preserve the class of g-frames for Hilbert C*-modules. Moreover, a necessary and suffcient condition is ob- ...

This article presents an analytic approach to study admissibility conditions related to classical full wavelet systems over finite fields using tools from computational harmonic analysis and theoretical linear algebra. It is shown that for a large class of non-zero window signals (wavelets), the generated classical full wavelet systems constitute a frame whose canonical dual are classical full ...

Abstract The dual-frame formalism leads to an approach extend numerical relativity simulations in generalized harmonic gauge (GHG) all the way null infinity. A major setback is that without care, even simple choices of initial data give rise logarithmically divergent terms would result irregular variables and equations on compactified domain, which turn prevent accurate approximation. It has be...

We construct dual formulation of linearised gravity in first order tetrad formalism in arbitrary dimensions within the path integral framework following the standard duality algorithm making use of the global shift symmetry of the tetrad field. The dual partition function is in terms of the (mixed symmetric) tensor field Φ[ν1ν2···νd−3]ν in frame-like formulation. We obtain in d-dimensions the d...
