通过分析比较3种聚焦效果较好的清晰度评价函数，提出了一种基于聚焦窗口模式的平方梯度函数作为聚焦评价函数，建立了评价函数的数学模型，并给出了实验分析和结果。与以往常用的评价函数相比，具有更高的可靠性和聚焦灵敏度(Compared by analyzing the three kinds of focus better clarity evaluation function, a model based on the focus window as a function of the square gradient focusing evaluation function, the establishment of the evaluation function of the mathematical model, and gives the experimental analysis and results. Commonly used in previous evaluation function, compared with higher reliability and sensitivity Highlights)

设X[ 0 : n - 1]和Y[ 0 : n – 1 ]为两个数组，每个数组中含有n个已排好序的数。找出X和Y的2n个数的中位数。  编程任务 利用分治策略试设计一个O (log n)时间的算法求出这2n个数的中位数。 数据输入 由文件input.txt提供输入数据。文件的第1行中有1个正整数n（n<=200），表示每个数组有n个数。接下来的两行分别是X，Y数组的元素。结果输出 程序运行结束时，将计算出的中位数输出到文件output.txt中(Let X [0: n- 1] and Y [0: n- 1] for the two arrays, each array containing the n number has been sorted. 2n X and Y to identify the number of digits.  programming tasks using the divide and conquer strategy try to design an O (log n) time algorithm to calculate this median number 2n. Data input by the input data provided input.txt file. The first line in the file has a positive integer n (n < = 200), that there are n numbers of each array. The next two lines are the X, Y array elements. The end result is output program runs, the calculated median output to file output.txt)
