Description: we embed watermarks in the original circles. In this way, the synchronization issue for watermark embedding and detecting can be best solved. Simulation results show that this method can resist variety of Geometry Attack, such as rotation, scaling, shearing and other common signal attacks.

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.)
