  • DCT,DWT,DFT,LSB数字水印MATLAB+GUI界面
    说明:  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 project is based on MATLAB wavelet transform DWT and discrete cosine DCT multi method contrast digital watermarking system. With GUI interactive interface. There is a main interface GUI, which can call the sub interfaces of DWT method and DCT method. The process includes: reading host image and watermark image, embedding, attacks of various methods (cutting, adding noise, rotation, etc.), extracting. Finally, PSNR peak signal-to-noise ratio is used to evaluate the robustness of different attacks.)

  • 小波边缘检测
    说明:  数学地角度来看,信号与图像处理可以统一看作是信号处理(图像可以看作是二维信号),在小波分析地许多分析的许多应用中,都可以归结为信号处理问题。对于其性质随时间是稳定不变的信号,处理的理想工具仍然是傅立叶分析。但是在实际应用中的绝大多数信号是非稳定的,而特别适用于非稳定信号的工具就是小波分析。(Mathematically, signal and image processing can be regarded as signal processing (image can be regarded as two-dimensional signal). In many applications of wavelet analysis, they can be reduced to signal processing. For signals whose properties are stable over time, the ideal tool for processing is still Fourier analysis. However, most of the signals in practical applications are unstable, and the tool especially suitable for unstable signals is wavelet analysis.)
