VS2013 configure opencv

These days, I am busy carrying out my last experiments named “video anomaly detection” for my thesis. For extracting features of video, I would use some functions of opencv, so I configured opencv in VS2013, here are some steps.

Environment

• C++ IDE: VS2013 Ultimate
• opencv version: 2.4.8
• operating system: win8

Step 1: install opencv and configure

download opencv and extract to your file folders. Here I extracted it to F:/program files.

Then we need to configure environment variables for opencv.

#add system variable -- Path
F:\program files\opencv\build\x86\vc12\bin

#add user variable -- opencv
F:\program files\opencv\build
#add it to PATH
F:\program files\opencv\build\x86\vc12\bin

pay attention:
please choose X86, whether your system is 32bit or 64bit, otherwise some errors will occur when you compiles.

Step2: Configure opencv in VS2013

Firstly, we create a new visual C++ project.
Then follow the pic below. We need to change three places.

1. VC++目录

   #add:
   F:\program files\opencv\build\include
   F:\program files\opencv\build\include\opencv
   F:\program files\opencv\build\include\opencv2

2. 库目录

   #add:
   F:\program files\opencv\build\x86\vc12\lib

3. 连接器－>输入－>附加依赖项

   #add:
   opencv_calib3d248d.lib
   opencv_contrib248d.lib
   opencv_core248d.lib
   opencv_features2d248d.lib
   opencv_flann248d.lib
   opencv_gpu248d.lib
   opencv_highgui248d.lib
   opencv_imgproc248d.lib
   opencv_legacy248d.lib
   opencv_ml248d.lib
   opencv_nonfree248d.lib
   opencv_objdetect248d.lib
   opencv_ocl248d.lib
   opencv_photo248d.lib
   opencv_stitching248d.lib
   opencv_superres248d.lib
   opencv_ts248d.lib
   opencv_video248d.lib
   opencv_videostab248d.lib

These files are in F:\program files\opencv\build\x86\vc12\lib.

Test: Convert Video to Image

/*实现视频的读取以及每一帧图像的保存*/

#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <opencv/cv.h>
#include <opencv/highgui.h>
using namespace std;

int main(int argc, char **argv)
{
	printf("------------- video to image ... ----------------n\n");
	//初始化一个视频文件捕捉器
	CvCapture* capture = cvCaptureFromAVI("F:/VS2012_workspace/OpticalFlowFarneback/qmul_junction.avi");
	//获取视频信息
	//定义和初始化变量
	int i = 0;
	IplImage* img = 0;
	char image_name[20];
	cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE);
	//读取和显示
	int num = 0;
	char command[100];
	char path[100];
	int n = 0;
	while (1)
	{
		img = cvQueryFrame(capture); //获取一帧图片
		if (!img) break;
		cvShowImage("mainWin", img); //将其显示
		cvWaitKey(20);
		sprintf(image_name, "%s%d%s", "image", ++i, ".jpg");//保存的图片名
		char filepath[100];
		sprintf(filepath, "%s%s%s", path, "\\", image_name);
		cvSaveImage(filepath, img);   //保存一帧图片
			}
	cvReleaseCapture(&capture);
	cvDestroyWindow("mainWin");
	return 0;
}
