Question

我尝试使用opencv版本2.4.6编译此源代码以加载和显示图像。我认为应该没有错误，因为我在互联网上获得了这些代码。但我仍然遇到一些错误，我不知道如何解决它。

我的代码：

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

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;
}

错误来自其他文件。我猜它来自图书馆。我不知道我是否错误地将opencv与我的devc ++相关联。但我想我已经按照给出的所有步骤做了正确的事。

请帮帮我！我不明白错误所在的代码。

这些是错误：

这些错误来自opencv目录中core文件夹中的文件operations.cpp。

我确实需要帮助，因为我是带图像的代码的初学者。

感谢任何帮助！感谢
