In this paper, we propose a novel prediction-based reversible steganographic scheme
based on image inpainting. First, reference pixels are chosen adaptively according to the …

In this paper, a reversible data hiding method with contrast enhancement is presented for
medical images. Firstly, image background segmentation is performed and the principal …

Quantum computation has the ability to solve some problems that are considered inefficient
in classical computer. Research on Quantum image processing has been extensively …

Conventionally, data embedding techniques aim at maintaining high-output image quality so
that the difference between the original and the embedded images is imperceptible to the …

In this paper, we propose a high capacity reversible data hiding method for 2D vector maps
based on virtual coordinates. In the scheme, we calculate two virtual coordinates for each …

In this paper, a new reversible data hiding method based on sorting and prediction in digital
images is proposed. The proposed method can embed two bits in the 3× 1 sub-block at …

Isosurfaces are commonly used to visualize scalar fields. Critical isovalues indicate
isosurface topology changes: the creation of new surface components, merging of surface …

In this paper, a reversible data hiding scheme is proposed based on histogram shifting of n-
bit planes (n BPs). This scheme extracts n BPs from an 8-bit plane for each pixel to generate …

In this paper, we propose a new algorithm in reversible data hiding, with the characteristics
of ease of implementation, based on the alteration of difference values relating to original …

Combined with the linear prediction-minimum mean squared error (LP-MMSE), an efficient
perceptual hashing algorithm based on improved spectral entropy for speech authentication …
