Can't display image in Visual Studio 2015

Question

Here's my code:

#include<opencv2/core/core.hpp>
#include<opencv2/highgui/highgui.hpp>
#include<iostream>

using namespace std;
using namespace cv;

int main()
{
    Mat image;
    cout << "This image has " << image.rows <<" rows and "<<image.cols<<" columns"<< endl;
    image = imread("images.jpg");
    if (image.empty()) {
        cout << "Image not read properly" << endl;
        getchar();
        return 0;
    }
    cout << "The size of the image is " << image.rows << " rows and " << image.cols << " columns." << endl;
    cout << "This image has " << image.channels() << " channels." << endl;
    namedWindow("Original_Image",CV_WINDOW_AUTOSIZE);
    imshow("Original_Image", image);
    waitKey(0);
    return 0;
}

The window which should display the image is just blank. I'm using Visual Studio 2015, OpenCV 3.2.0.

如果图像路径错误，您可能会得到一张空白图片。空白窗口由namedWindow语句给出，该语句只是创建窗口。尝试在imread中提供图像的完整路径（例如，如果您的图像保存在下载下，请将文件路径用作“C：\\ Users \\ name \\ Downloads \\ image.jpg”）。确保在指定文件路径时使用双反斜杠（在基于linux的系统中使用正斜杠，在Windows中使用反斜杠!!）。
