这是一组二维小波变换的经典程序，对研究小波的很有用，里边有对应说明-This is a group of two-dimensional wavelet transform of the classical procedures, the study of wavelets useful, inside there is the corresponding description

emd算法部分程序，建议刚学习的同学看看，很有价值的！-EMD algorithm part of the program, proposed just learning students see great value!

这个Matlab程序的最主要功能在water.m文件中，当你调用这个函数之后，系统会提示你给哪个图像文件加水印。blockdwt2.m文件，用于在小波频域添加水印logo图片。dmg.m文件产生水印logo图片。watdet3.m文件中的函数实现的功能是检查是否有水印的logo存在。-The main function of Matlab procedures in water.m document, when you call this function, the system will prompt you to add a watermark image files which. blockdwt2.m documents, for the wavelet frequency domain to add a watermark logo image. dmg.m document generated picture watermark logo. watdet3.m realize a function of the document
