信号瞬时相关函数的傅立叶变换 wvd
Wigner-Ville 分布(简称 WVD)是典型的二次型变换，它定义为信号瞬时相关函数的傅立
叶变换。
由于在计算中不加窗操作，它避免了时域分辨率和频域分辨率之间的相互牵制。
已证明，对于单分量线性调频信号，WVD 的时频表示能量集中性最优。但也正因为不涉
及窗函数，在分析多分量信号时 WVD 会受到交叉项的干扰。(The Wigner-Ville distribution (WVD) is a typical quadratic transformation, which is defined as the Fourier of the instantaneous correlation function of a signal.
Ye Bianhuan.
Because of no window operation in the calculation, it avoids the mutual restraint between time domain resolution and frequency domain resolution.
It has been proved that for the single component LFM signal, the WVD time frequency representation has the best energy concentration. But it is also because it does not involve.
And window functions, when WVD is used to analyze multi-component signals, it will be interfered by cross terms.)

研一刚上完数值分析，自己写了几个算法的子函数，可以直接调用，参数的含意在文件中有说明，这五个算法分别是：拉格朗日插值，hermite插值，Newton插值，修正hamming算法，龙贝格加速算法。希望能够对大家有所帮助。(Kenichi just finished numerical analysis, himself wrote a number of algorithms Functions, you can directly call the meaning of the parameters described in the document, the five algorithms are: Lagrange interpolation, hermite interpolation, Newton interpolation value, as amended Hamming algorithm to accelerate the algorithm Romberg. We hope to be able to help.)

说明： 迭代法
迭代式阈值选取的基本思路是:首先根据图像中物体的灰度分布情况， 选取一个近似阈值作为初始阈值(Iterative threshold selected basic idea is: First, the gray-scale distribution of objects in the image, select an approximate threshold as initial threshold)
