Histogram and Vector Quantization based Multilevel Reversible Data Hiding Schemes [PDF]
, 2015 MT, CSEDData hiding techniques in digital images has been a topic of research for so many years. The role of data hiding is to embed secret data in the cover media at the sender side and retrieve the embedded secret data as well as the cover media at the

Advanced Science, EarlyView.Fibronectin 1 (FN1)‐expressing subicular subpopulations encode novel object preference and selectively govern retrieval of novel object recognition (NOR) via affecting excitability of entorhinal‐projecting circuit through large conductance Ca2+‐activated potassium (BK) channel. ABSTRACT Novel object recognition (NOR), referring to the cognitive ability

Reversible Data Hiding Based on Geometric Structure of Pixel Groups [PDF]
, 2016 [[abstract]]Many reversible data hiding schemes have been developed in recent decades. Traditional schemes typically must deal with the problem of overflow and underflow, or transmission of hiding parameters.

Advanced Science, EarlyView.This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...

Reversible data hiding based on wavelet spread spectrum [PDF]
, 2004 This paper presents a reversible data hiding method based on wavelet spread spectrum and histogram modification. Using the spread spectrum scheme, we embed data in the coefficients of integer wavelet transform in high frequency subbands.

REVERSIBLE IMAGE DATA HIDING WITH CONTRAST ENHANCEMENT [PDF]
, 2016 Reversible data hiding (RDH) continues to be intensively studied locally of signal processing. To judge the performance of the RDH formula, hiding rate and marked picture quality are essential metrics.

Advanced Science, EarlyView.Mid‐infrared photothermal imaging enables multidimensional profiling of micro‐ and nanoplastics in bottled water. A total of 9.9 × 104 particles L−1 is detected, with 64% in the nanoscale regime. Spectral evolution, including peak narrowing and band shifts, reveals local chain reorganization in polyethylene terephthalate (PET), highlighting intrinsic ...
