搜索算法是利用计算机的高性能来有目的的穷举一个问题的部分或所有的可能情况，从而求出问题的解的一种方法。( The searching algorithm has a goal exhaustion question part or all possible situations using computer s high performance, thus extracts the question the solution one method. )

Okumura analyzed path-loss characteristics based on a large amount of experimental data collected around Tokyo, Japan. He selected propagation path conditions and obtained the average path-loss curves under flat urban areas. Then he applied several correction factors for other propagation conditions, such as: Antenna height and carrier frequency Suburban, quasi-open space, open space, or hilly terrain areas Diffraction loss due to mountains Sea or lake areas Road slope Hata derived empirical formulas for the median path loss (L50) to fit Okumura curves.

数字滤波器,仿真成功为低通滤波器.一个典型的滤波器的仿真 比较详细 还有图(digital filters, the success of the simulation low-pass filter. A typical simulation of the filter there are also more detailed)

Tsai标定算法的精度验证程序，用matlab编写，可以画出重建图像(Tsai calibration algorithm for the accuracy of the verification process, the preparation of matlab, you can draw the reconstructed image)

逆变器仿真程序,模拟AC-DC，需要者可以参考(Inverter simulation, simulation of AC- DC, those can be reference )

频谱细化的程序，信号分析的强大工具，很好用！(Spectrum refinement of the program, a powerful tool for signal analysis, easy to use!)

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.
