Description: 将具有特定标识的信息隐藏在数字化图像、视频、音频等多媒体。是一种基于DCT变换和ARNOLD置乱技术的数字图像水印算法，首先通过Arnold置乱二值水印图像对水印图像进行加密，其次将加密后的图像选择适合的强度，在载体图像中选择低频信号的位置进行嵌入。适合用于简单的图片版权保护。(Information that has a specific identity is hidden in digital image, video, audio and other multimedia. Is a kind of based on DCT transform and ARNOLD scrambling technology of digital image watermarking algorithm, first by ARNOLD scrambling binary watermark image of watermark image is encrypted, then will choose suitable strength, the encrypted image in the image embedded in select the location of the low frequency signal. Suitable for simple image copyright protection.)

Description: 本课题为基于MATLAB的小波变换dwt和离散余弦dct的多方法对比数字水印系统。带GUI交互界面。有一个主界面GUI，可以调用dwt方法的子界面和dct方法的子界面。流程包括，读取宿主图像和水印图像，嵌入，多种方法的攻击（剪切，加噪，旋转等），提取，最后利用psnr峰值信噪比进行评价不同攻击下，鲁棒性的好坏。(This topic is based on MATLAB wavelet transform DWT and discrete cosine DCT multi method comparison digital watermarking system. With GUI interface. There is a main interface GUI, which can call the sub interface of DWT method and DCT method. The process includes: reading host image and watermark image, embedding, attack of various methods (cutting, adding noise, rotation, etc.), extracting, and finally evaluating the robustness of different attacks by using PSNR peak signal-to-noise ratio.)
