摘要
在MATLAB环境下实现了基于人眼视觉特性的DCT域彩色图像的信息隐藏。经过对DCT变换的特征分析,选用载体图像DCT系数的中频部分作为待隐藏图像的DCT系数。实验结果表明,嵌入隐藏信息后的两幅图像在视觉上人眼无法分辨,算法具有良好的隐秘性和较强的鲁棒性。
In this paper it realized colorized image information hiding in DCT domain based on human visual characteristic using MATLAB Toolbox. By the characteristic analysis carried on DCT transformation, middle frequency section in DCT coefficient of carrier images is selected as DCT coefficient of the images to be hided. The experimental results indicate that people can not differentiate by human vision two pictures with the hiding information embedded. This algorithm possesses very good steganography and strong robustness.
