用基于小波变换的方法采用coif5小波对信号进行谐波分析-Wavelet Transform-based Methods coif5 harmonic wavelet analysis of signals

这是自己编的一个用于检验形心的代码，希望对大家有用，欢迎下载-This is an own centroid for testing code, I hope useful for all of us are welcome to download

可以用CDF53小波对灰度图像实现正反变换-CDF53 wavelet can be used to achieve positive and negative gray image transformation

图像正交变换，包括傅里叶变换，离散余弦变换，沃尔什变换，小波变换等-Orthogonal transformation images, including Fourier transform, discrete cosine transform, Walsh transform, wavelet transform, etc.

对bmp图像的小波变换，包括其应用，如图像的滤波-bmp image of the wavelet transform, including its applications, such as image filtering

用一维小波变换进行图像去噪处理，有较低的计算复杂度，提高效率和计算速度。-Victoria with a wavelet transform image denoising, lower computational complexity, increase efficiency and speed.

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
