Image RVB en image binaire à l'aide d'OpenCV

Donc, je suis super noob et je suis en train de faire quelque chose que de convertir une image RVB de l'image binaire en C/C++, à l'aide d'OpenCV. Mon premier programme était-ce:

#include <opencv.hpp>

using namespace cv;

int main ( int argc, char **argv )
{
Mat im_gray = imread("img1.png",CV_LOAD_IMAGE_GRAYSCALE);

Mat im_rgb  = imread("img.png");
Mat im_gray;
cvtColor(im_rgb,im_gray,CV_RGB2GRAY);

Mat img_bw = im_gray > 128;

imwrite("image_bw.jpg", img_bw);

return 0;
}

Mais il dit: "Il y avait des erreurs de build" et il ouvre juste l'image d'origine. Comment puis-je faire droit? Quelqu'un peut-il m'aider?

La sortie a été:

PS.: L'Utilisation De Windows 8 + Visual Studio 10 + OpenCV 2.3.

L'image que je suis en train de convertir l'image binaire: img1.png

Vous avez mentionné le dll dans le msg d'erreur dans `C:\Windows\System32` ?

à retirer l'excédent de Mat im_gray; et comprennent chemin d'accès est défini sur OpenCV2.3/build/include et le programme compile.

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace cv;
int main ( int argc, char **argv )

Mat im_rgb  = imread("img.png");
cvtColor(im_rgb,im_gray,CV_RGB2GRAY);
Mat img_bw = im_gray > 128;
imwrite("image_bw.jpg", img_bw);
return 0;
}

#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
using namespace cv;
int main( int argc, char** argv )
{
Mat img = imread( "C:/test/img1.png");
cvtColor(img,img,CV_BGR2GRAY);
Mat left=img(Rect(0,0,300,151));
Mat right=img(Rect(300,0,img.cols-300,151));

threshold(right,right,0,255,CV_THRESH_OTSU);
imshow("img",img);

}

Merci pour la réponse. J'ai mis 77 istead de 128 (Mat img_bw = im_gray > 128;) j'étais le meilleur, mais encore certains numéros sont incomplètes. Une idée de comment je peux résoudre ce problème? Voici le résultat docs.google.com/file/d/0BzUNc6BOkYrNNVNFZzAtenpvaWM/...
