Adaptive reversible data hiding for JPEG images
TL;DR: In this article, the authors proposed an improved method of the reversible data hiding for JPEG images proposed by Xuan et al. They found that the blocks, located in the noisy part of the image, are not suitable for embedding data and proposed a method to judge whether a block consisted of 8 times 8 DCT coefficients is located in smooth part of image by using the DC coefficient of neighboring blocks.
