说明：  一种核密度估计，或者称作带宽选择的方法，可以估计二维尺度参数，至于多维以上的估计方法尚在开发，多维情况下个人经验好的方法是多次实验取较好值(kernel density estimation, bandwidth selection, two-dimensional scale parameter can be estimated ,for the multi-dimensional approaches are still under development, multi-dimensional cases, personal experience is to do the experiment many times)

画圆，，复杂背景下，圆心的中心定位，使用的是霍夫变换(Circle, complex background, the center of the circle' s center position, using a Hough transform)

信号的循环卷积，离散傅里叶变换，产生理想低通滤波器h(n)的函数(Signal of the circular convolution, discrete Fourier transform, resulting in an ideal low-pass filter h (n) function)
