vs2010 命令行參數的簡單寫法
謝謝師兄告訴的方法，可以寫到播客裏麵。。
在工程屬性頁的“調試”一欄裏麵，可以將命令參數當做dos cmd窗口下的命令行輸入，
順便附上代碼吧，這個代碼是opencv官方樣例裏麵的：
#include "opencv2/core/core.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/video/background_segm.hpp"
#include "opencv2/highgui/highgui.hpp"
#include <stdio.h>
using namespace std;
using namespace cv;
static void help()
{
printf("\nDo background segmentation, especially demonstrating the use of cvUpdateBGStatModel().\n"
"Learns the background at the start and then segments.\n"
"Learning is togged by the space key. Will read from file or camera\n"
"Usage: \n"
" ./bgfg_segm [--camera]=<use camera, if this key is present>, [--file_name]=<path to movie file> \n\n");
}
const char* keys =
{
"{c |camera |true | use camera or not}"
"{fn|file_name|tree.avi | movie file }"
};
//this is a sample for foreground detection functions
int main(int argc, const char** argv)
{
help();
CommandLineParser parser(argc, argv, keys);
bool useCamera = parser.get<bool>("camera");
string file = parser.get<string>("file_name");
VideoCapture cap;
bool update_bg_model = true;
if( useCamera )
cap.open(0);
else
cap.open(file.c_str());
parser.printParams();
if( !cap.isOpened() )
{
printf("can not open camera or video file\n");
return -1;
}
namedWindow("image", CV_WINDOW_NORMAL);
namedWindow("foreground mask", CV_WINDOW_NORMAL);
namedWindow("foreground image", CV_WINDOW_NORMAL);
namedWindow("mean background image", CV_WINDOW_NORMAL);
BackgroundSubtractorMOG2 bg_model(20,5,true);//(100, 3, 0.3, 5);
Mat img, fgmask, fgimg;
for(;;)
{
cap >> img;
if( img.empty() )
break;
//cvtColor(_img, img, COLOR_BGR2GRAY);
if( fgimg.empty() )
fgimg.create(img.size(), img.type());
//update the model
bg_model(img, fgmask, update_bg_model ? 0.5 : 0);
fgimg = Scalar::all(0);
img.copyTo(fgimg, fgmask);
Mat bgimg;
bg_model.getBackgroundImage(bgimg);
imshow("image", img);
imshow("foreground mask", fgmask);
imshow("foreground image", fgimg);
if(!bgimg.empty())
imshow("mean background image", bgimg );
char k = (char)waitKey(30);
if( k == 27 ) break;
if( k == ' ' )
{
update_bg_model = !update_bg_model;
if(update_bg_model)
printf("Background update is on\n");
else
printf("Background update is off\n");
}
}
return 0;
}
