自己搭的三相锁相环模拟电路，作业经过运行验证，能够很迅速的锁定电压电流相位。(Take their own three-phase PLL analog circuits, after running the verification, the lock can be very rapid phase of voltage and current.)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

数据频域分解法，可能不是很全面，可以利用的这个方法的代码很少，本人也是从网上找的，可能不好理解，大家看看参考把(Data in the frequency domain decomposition method, may not be very comprehensive, code can use this method rarely, I also find from the Internet, you may not understand, we look at the reference to)
