Data Hiding Method for Color AMBTC Compressed Images Using Color Difference

چکیده
Image compression technology and copyright protection are certainly the important technologies for free exchange of multimedia. For an image, we propose a color Absolute Moment Block Trucation Coding (AMBTC) method using common bit-plane created by k-means. In addition, data hiding based on AMBTC Optimal Pixel Adjustment Process (OPAP) was proposed confidential secret communication. The number quantization levels is nine per block. Therefore, edge compressed image can be expressed more delicately. As result simulation, it seen that close to original image. Moreover, performance also obtained excellent results. experiment, measured quality Color Difference (CD) proposed, measurement very satisfactory.

High Capacity Reversible Data Hiding in AMBTC-Compressed Images
This paper proposes a high capacity reversible data hiding scheme in images compressed by absolute moment block truncation coding (AMBTC). The quantization levels of compressed blocks are employed as cover media, and some extra confidential data are hidden in it based on a multilevel histogram shifting mechanism. The transmission system preserves the same complexity. Moreover, the reconstructed...
متن کاملA Robust Method for Data Hiding in Color Images
In this paper, we propose a methodology for embedding watermark image data into color images. At the transmitter, the signature image is encoded by a multiple description encoder. The information of the two descriptions are embedded in the host image in the spatial domain in the red and blue components. Furthermore, this scheme requires no knowledge of the original image for the recovery of the...

ÐIn an earlier paper [4], we proposed a steganography scheme for hiding a piece of critical information in a host binary image. That scheme ensures that, in each m n image block of the host image, as many as blog2 mn 1c bits can be hidden in the block by changing at most 2 bits in the block. In this paper, we propose a new scheme that improves [4] in its capability to maintain higher quality ...
