FDTD for Wave equation1

说明：  VMD是通过迭代搜寻变分模型（具体怎么搜寻，请亲们自己看，我主要讲他的大概）最优解， 来确定我们所知的模态uk(t)及其对应的中心频率ωk和带宽。 每个模态都是具有中心频率的有限带宽（就是在频域中有在一定的宽度）。所有模态之和为源信号。(VMD is to determine the modal UK (t) and its corresponding central frequency, k and bandwidth by iteratively searching for the optimal solution of the variational model (see dear friends for details, and I will mainly talk about his approximate solution). Each mode is a finite bandwidth with a central frequency (that is, a certain width in the frequency domain).The sum of all modes is the source signal.)

说明：  简单的 关于图像的二值化 锐化 滤波 基本能实现 算出不变矩！！！！！关于图像检索(Simple binary on the image sharpening filter can basically figure out the same moment to achieve! ! ! ! ! About Image Retrieval)

小波分析，用于时间序列的周期性分析，更换函数即可使用(Wavelet analysis is used for periodic analysis of time series, and can be used to replace functions.)
