对于多个有差频的平行光的干涉，可以产生移动的条纹-multiple optical interference fringe

利用二维离散小波变换技术实现数字水印，并给出水印图像检测结果-The use of two-dimensional discrete wavelet transform of digital watermarking technology, and gives test results watermark images

小波分析的讲座，小波分析一直是研究热点，此讲座很好-wavelet analysis lectures, wavelet analysis research has been a hot topic of this seminar very good

此程序用提升法实现第二代小波变换,采用时域实现,步骤先列后行-This procedure used to enhance law to achieve the second-generation wavelet transform, using time-domain realization of the first steps out later

小波变换源代码，用于图像分析，包括图像压缩、纹理分析和识别。-The program illustrates the original code of wavelet transformation, which can be used in image compression, texture analysis and recognization.

呵呵 额呵呵呵呵 额呵呵呵呵 额呵呵呵呵 额呵呵呵呵额-hehe

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

小波分析理论与Matlab 7实现.rar，希望对大家有帮助-Wavelet analysis theory and Matlab 7 to achieve. Rar, want to help everyone
