TL;DR: A new image steganographic technique capable of producing a secret-embedded image that is totally indistinguishable from the original image by the human eye is proposed, and the proposed scheme is secure against the RS detection attack.

TL;DR: Wang et al. as mentioned in this paper proposed an image steganographic technique capable of producing a secret-embedded image that is totally indistinguishable from the original image by the human eye, which avoids the falling-off-boundary problem by using pixel-value differencing and the modulus function.

TL;DR: This survey paper is focused on the development and current status of steganographic techniques for grayscale images, and shall separately introduce schemes with high hiding capacities and scheme with high imperceptibility.

TL;DR: A novel adaptive steganographic scheme that is capable of both preventing visual degradation and providing a large embedding capacity superior to that offered by a number of existing schemes is presented.

TL;DR: This paper presents a low distortion data embedding method using pixel-value differencing and base decomposition schemes, which is capable of embedding large amounts of a message, yet still produces the embedded image with very low distortion.
