OpenCV中的Graphcut会产生奇怪的错误

我有这个代码：

int main()
{    
     Mat image0=imread("C:\Working Dir\Tests\TestBlending\image0.jpg");
     Mat image1=imread("C:\Working Dir\Tests\TestBlending\image1.jpg");
     // our corners are just at (0,0)
     cv::Point corner1;
     corner1.x = 0;
     corner1.y = 0;
     cv::Point corner2;
     corner2.x = 0;
     corner2.y = 0;
     std::vector<cv::Point> corners;
     corners.push_back(corner1);
     corners.push_back(corner2);
     std::vector<cv::Mat> masks;
     Mat imageMask0;
     Mat imageMask1;
     masks.push_back(imageMask0);
     masks.push_back(imageMask1);
     std::vector<cv::Mat> sources;
     sources.push_back(image0);
     sources.push_back(image1);
     cv::detail::GraphCutSeamFinder *seam_finder = new cv::detail::GraphCutSeamFinder();
     seam_finder->find(sources, corners, masks);
     printf("%lun", masks.size());
     for(int i = 0; i < masks.size(); i++)
     {
          std::cout << "MASK = "<< std::endl << " "  << masks.at(i) << std::endl << std::endl;
      }
      return 0;
}

当我运行此代码时，我收到此错误：

OpenCV Error: Assertion failed (dims <= 2 && data && (unsigned)i0 < (unsigned)size.p[0] && (unsigned)(i1*DataType<_Tp>::channels) < (unsigned)(size.p[1]*channels()) && ((((sizeof(size_t)<<28)|0x8442211) >> ((DataType<_Tp>::depth) & ((1 << 3) - 1))*4) & 15) == elemSize1()) in unknown function, file C:slavebuildsWinInstallerMegaPacksrcopencvmodulescoreincludeopencv2/core/mat.hpp, line 537

失败位置的堆栈是：

我正在使用 OpenCV 2.4.6 （C++ 在 Visual Studio 2012 上）

生成此错误的此代码有什么问题？

是否有任何示例代码可以显示如何在混合之前使用 GraphCut 查找两个图像之间的接缝线？

编辑 1

我做了一些挖掘，发现问题出在这一行：

   subimg1.at<Point3f>(y + gap, x + gap) = img1.at<Point3f>(y1, x1);

这是在第 1241 行seam_finders.cpp。

问题是图像 1 不是浮点格式，因此 img1.at（y1， x1）; 生成错误。

我尝试将图像转换为浮动，这解决了问题，但也清除了图像中的所有数据。

所以我现在的代码是：

Mat image0=imread("C:\Working Dir\Tests\TestBlending\layer0000.jpg");
Mat image1=imread("C:\Working Dir\Tests\TestBlending\layer0001.jpg");
image0.convertTo(image0,CV_32FC3);
image1.convertTo(image1,CV_32FC3);

我可以看到图像已正确加载，但在转换为后它们都是空的（值为零）。

如何解决此问题？
