Question

我是编程的新手。我有一个问题，关于将循环的输出保存到.csv文件。

}

int testBlur(Mat sourceImage, Mat & destinationImage, float & time)
{

TIMER tic;

/// test parameters
int filterSize = 11;
int N = 1000;
int time1;
if( sourceImage.empty()) // Check for invalid input
{
cout <<  "Invelid input image" << std::endl ;
return -1;
}


for (filterSize =1; filterSize <11; filterSize+=1)
{
    SYS_reset_timer(&tic);  

for(int i =0; i<N; i++)
{
    // filter the image
    blur(sourceImage, destinationImage, cvSize(filterSize, filterSize));

}

SLONG elapsed_time = SYS_get_timer_us(&tic);
float elapsed_time_seconds = elapsed_time/1000.0f;
float el = (elapsed_time_seconds)/N;

cout<< "blur"<< el<<endl;
time = el;
}


return 0;

}

int main(int argc, const char* argv[])

{
Mat sourceImage, destImage, temp, desttImage, detect;
Mat grad,src,distanceTransform;
int scale = 1;
int delta = 0;
float time;
int ddepth = -1;    


////////
ofstream myfile;
myfile.open ("Elapsed Time For Image Filtering.csv");

//load image
sourceImage = imread("../images/man.tiff",IMREAD_GRAYSCALE); // load and convert to grayscale
if( sourceImage.empty() )                      // Check for invalid input                                           
{
cout <<  "Could not open or find the image" << std::endl ;
return -1;
}








// call test function for blur
testBlur(sourceImage, destImage,time);
myfile << "Blur;"<<time<<time<<endl;
imwrite("blur.bmp", destImage);

//show results
#ifdef  SHOW_RESULTS
namedWindow( "Display window", WINDOW_AUTOSIZE ); // Create a window for display.
imshow( "Display window", destImage );                // Show our image inside it.
//waitKey(0); // Wait for a keystroke in the window
#endif

我转换了图像并使用了一些过滤功能并添加了计时器来测试tick和toc，我通过挂起过滤器的值来添加for循环，并且我无法将testblur的十个输出保存到.csv文件。请告诉我如何将测试模糊的for循环输出打印到.csv文件。
