An Improved Reversible Data Hiding in Encrypted Image Method Based on Block Selection
IEEE Access, 2020 For reversible data hiding in encrypted image (RDHEI), the most important problem is the conflict between reversibility and embedding capacity. Reversibility has been realized by existing methods, however, the embedding capacity is still too low for ...

Visibility of quantization errors in reversible JPEG2000
Signal Processing: Image Communication, 2020 Image compression systems that exploit the properties of the human visual system have been studied extensively over the past few decades. For the JPEG2000 image compression standard, all previous methods that aim to optimize perceptual quality have considered the irreversible pipeline of the standard.

Analysis of round off errors with reversibility test as a dynamical indicator [PDF]
, 2021 We compare the divergence of orbits and the reversibility error for discrete time dynamical systems. These two quantities are used to explore the behavior of the global error induced by round off in the computation of orbits.

Identifying the space source term problem for time-space-fractional diffusion equation
Advances in Difference Equations, 2020 In this paper, we consider an inverse source problem for the time-space-fractional diffusion equation. Here, in the sense of Hadamard, we prove that the problem is severely ill-posed.

Reverse Checking of Quantum Algorithm Execution
IEEE Access, 2020 Verification of quantum computation is critical because undesirable interference and noise are major technical hurdles in quantum computing. We propose an approach for reverse checking of computation results that takes advantage of quantum teleportation ...

Flow and Heat Transfer in a Co-Rotating Cavity with Tubes: A Coupled Prediction Model [PDF]
Journal of Applied Fluid Mechanics, 2022 In previous studies, researchers established mathematical models for predicting the pressure coefficient in simple cavities and tubed vortex reducers based on the assumptions of incompressibility and adiabatic reversibility.
