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
