Thanks Daniil..

Hello Mr Daniil,

I downloaded OpenCV-2.4.2 and I couldn't find any exe(auto run) file there.How ever I extracted that in to my C:\ directory and followed the process in this video>> https://www.youtube.com/watch?v=cgo0UitHfp8&feature=plcp

I have VS 2008 version. According to the video First I Added OpenCV to system variables and next build Visual Studio project. Added all the libraries and completed according to the video.

But When I debug my project it says>> The application has failed to start because tbb_debug.dll was not found.

So Mr Daniil, 1)Are there any wrong in my installation or this video? 2)Did I completed the installation process correct?

Thank U.

Hello sammy, I'm new to these things..could u please tell me which line should I change to show the image.Or how I show the image using open CV.What's wrong with this?

I'm using OpenCV2.4.2 and Visual Studio 2008

This is the error message

The program '[4060] OpenCV_sample.exe: Native' has exited with code -1 (0xffffffff).

This is the sample program

I included all the libraries which need here. using namespace cv; using namespace std;

int main( int argc, char** argv )
{ 
if( argc != 2) 
{
 cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
 return -1;
}

Mat image;
image = imread(argv[1], CV_LOAD_IMAGE_COLOR);   // Read the file

if(! image.data )                              // Check for invalid input
{
    cout <<  "Could not open or find the image" << std::endl ;
    return -1;
}

namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
imshow( "Display window", image );                   // Show our image inside it.

waitKey(0); // Wait for a keystroke in the window
return 0;
}

Hello Mr.Daniil,

First many thanks 4 your reply.

So I have simple problem. When we install OpenCV using pre-built libraries;

1.First we have to install CMAKE.

2.Then Extract OpenCV and configure opencv with visual studio using CMAKE.

3.Next add OpenCV library to the system path.

Are these steps correct?..So is the use of the CMAKE is configure opencv with Visual Studio?What is the use of CMAKE?

I must be thankful to u if u kindly answer these questions.

Thank U.

Hello,

I need 2 know the Difference between Installation OpenCV

1. By Using the Pre-built Libraries ?
2. By Making Own Libraries from the Source Files ?

When we do first one we have to only download OpenCV new version and extract it, and configure it with Visual studio using CMake.

But why we are going to download OpenCV libraries and others using TortoiseGit hub(it takes many time) ? Are there any special advantage of that?

Could u please answer these questions...

Thank U, Elec.

Hello Everyone,

Unable to connect to a repository at URL 'http://code.opencv.org/svn/opencv/trunk' Could not open the requested SVN filesystem

3)Can I use OpenCV-2.4.2.exe,cmake-2.8.9-win32-x86 & TortoiseSVN-1.7.10.23359-win32-svn-1.7.7 on my OS..?If not what should I use?
