Description: 此程序用提升法实现第二代小波变换
我用的是非整数阶小波变换
采用时域实现,步骤先列后行
正变换：分裂，预测，更新；
反变换：更新，预测，合并
只做一层（可以多层，而且每层的预测和更新方程不同）-procedure used to upgrade Method second generation wavelet transform I use a non-integer-order wavelet transform domain when used, the first step out go backward transformation : split and forecast updates; Anti-Transform : Update, forecasting, consolidations only one (which can be multi-storey, but each floor and update the forecast equation different) Platform: |

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.)
