だから、私は超初心者で、OpenCV を使用して C/C++ で RGB イメージをバイナリ イメージに変換しようとしています。私の最初のプログラムはこれでした：

#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;
}

しかし、「ビルドエラーがありました」と表示され、元の画像だけが開きます。どうすれば正しくできますか？誰でもこれで私を助けることができますか?

出力は次のとおりです。

PS .: Windows 8 + Visual Studio 10 + OpenCV 2.3 を使用しています。

remove extraMat im_gray;と include path が設定されOpenCV2.3/build/include、プログラムがコンパイルされます。

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.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");
    cvtColor(im_rgb,im_gray,CV_RGB2GRAY);

    Mat img_bw = im_gray > 128;

    imwrite("image_bw.jpg", img_bw);

    return 0;
}

編集：ここに画像の説明を入力

#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(left,left,0,255,CV_THRESH_OTSU);
    threshold(right,right,0,255,CV_THRESH_OTSU);
    imshow("img",img);
    waitKey(0);
    return 0;
}
