Summary: In this letter, an efficient 2D mapping strategy is proposed by considering error pairs on two diagonal lines of the 2D prediction error histogram (PEH). The proposed method can quickly adapt to different frequencies of error pairs for various mapping area sizes, resulting in satisfactory embedding performance.

Summary: Reversible data hiding (RDH) has been studied for over two decades and can be divided into RDH and reversible data hiding in encrypted images (RDHEI) depending on the application scenario. Most studies have focused on gray-scale images, with relatively few conducted on color images and even fewer on palette images. Therefore, a new framework specifically for palette images is proposed, which includes a route selection algorithm followed by a color table reconstruction. Experimental results demonstrate the improvement brought by this route selection to existing RDH/RDHEI methods in palette images.

Summary: A grayscale-invariant RDH method is proposed in this work, which reduces the need for correction bits by using a self-correcting mechanism and a relational approach to preserve grayscales and embed more message bits into some green scales. Experimental results show significant improvement in embedding capacity and rate-distortion performance compared to previous works.

Summary: In this paper, a color image reversible data hiding scheme based on channels united embedded is proposed, which utilizes pixel value ordering (PVO). The scheme improves the fidelity of the image by combining channel unity embedding (CUE) method and pairwise prediction error expansion (PEE) strategy, achieving significant superiority over state-of-the-art schemes.

Summary: This paper presents an innovative approach for invertible color-to-grayscale conversion by independently compressing the chromaticity plane and embedding it into the luminance plane as a watermark. Experimental results demonstrate that using least significant bit substitution can achieve high-quality synthesized grayscale and reconstructed color images simultaneously.

Summary: Invertible color-to-gray algorithms are effective in protecting color images in storage, transmission, or limited-access environments by hiding color information in a gray-scale version of the image. This paper proposes a reversible distortion of the protected gray-scale image to enhance illegal reconstruction difficulty while preserving general visibility. Additionally, a visible imperceptible watermark is embedded to protect ownership of the colorized image in public access.
