小波变换的数字水印算法,附有论文和源程序.(Wavelet Transform Digital Watermarking Algorithm with thesis and source code.)

在labview中进行小波分析程序设计，内容最全、最好的文件，参照本文件可以直接一步步编写小波分析程序，适合初学者。(The labview wavelet analysis program design, the most comprehensive, best file reference in this document can step directly Step preparation of a wavelet analysis program for beginners.)

在 MATLAB 中的窗函数,十分简单： 矩形窗 三角窗 汉宁窗 海明窗 布拉克曼窗 恺撒窗 (In MATLAB, the window function is very simple: a rectangular window of triangular windows Hanning Hamming Blackman Window Caesar Window)

将图像按位平面分解，然后在最低有效为嵌入一定的信息，达到数字隐藏的作用，是最原始的数字水印技术(image caput plane decomposition, and then embedded in the lowest effective for certain information, to hide the figures, is the most primitive digital watermarking technology)

简单的方向滤波器， 带测试图的， 可以直接运行(Simple directional filter, with a test chart, you can directly run)

离散小波变换的简单程序，适合初学者学习，附有通用函数。(Simple procedures discrete wavelet transform, suitable for beginners to learn, with common functions.)

说明：  给出了在matlab环境下的源代码，经过了上机调试，可以实现小波变换对图像的二次压缩！(given Matlab environment in the source code, after the Machine, can achieve a wavelet transform of the second image compression!)
