CDF 9 / 7小波变换的matlab代码

某一直升机齿轮箱上的早期损伤的特征是，在伴随振动信号上产生一个可变周期的非平稳扰动信号。要求按此特征构造一组有物理意义的数据仿真早期故障信号，应用小波变换技术分析故障的特征和发生时刻。-a helicopter gearbox early on the characteristics of the injury, In addition to the vibration signal produced a variable cycle perturbation of non-stationary signals. Click here to request a group of tectonic significance of a physical early fault simulation data signals Application of wavelet transform technical analysis of the features and fault occurred moments.

小波变换是一个当今比较常用的图像处理方法，它可以很方便实现图像空间域到频率域的转换！-wavelet transform is a more commonly used in today"s image processing method, which can facilitate the achievement of image space domain to the frequency domain conversion!

详细介绍了小波变换的相关知识-Detailed knowledge of the wavelet transform

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

提供两种常用滤波方法的VC源程序，已经运行通过。-offers two commonly used methods of filtering source VC has been running through.

有两个vc工程文件，分别是lzc编码和解码。算法主要可以对灰度图像进行压缩和解压缩，效果比jpeg要好。其实这就是jpeg2000的原型。-two vc engineering documents were lzc encoding and decoding. This algorithm can be gray image compression, the effect is better than jpeg. This is actually the prototype JPEG2000.
