1.滤波

GaussianBlur(imgThresholded, imgThresholded, Size(5, 5), 0, 0);//高斯滤波

medianBlur(imgThresholded, imgThresholded, 3);//中值滤波

bilateralFilter(imgThresholded, imgThresholded, 5, 10.0, 2.0);//双边滤波

blur(imgThresholded, imgThresholded, Size(3, 3));//均值滤波

2.计算运行时间

#include "time.h" //添加头文件

{    

clock_t start, finish;
start = clock();//待检测程序首部

.... ...//待测程序

finish = clock();
printf("共耗时%.3lf秒", ((double)finish - start) / 1000);  //待检测程序尾部

  }
