I tried finally and i got the masks updated and they contain black and white regions (i passed white masks) is it right a output?

I found that the result of it is strange ,the mask is all white or all black.Now I want to know how to use GraphCut to find seeam line between two overlapping two images.thanks! int main() {
Mat image0=imread("F:\1\1.jpg"); Mat image1=imread("F:\1\2.jpg"); image0.convertTo(image0,CV_32F,1.0/255.0); cv::imshow("image0",image0); image1.convertTo(image1,CV_32F,1.0/255.0); // 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;
 Mat imageMask0(image0.size(),CV_8U);
 imageMask0(Rect(0,0,imageMask0.cols,imageMask0.rows)).setTo(255);
 Mat imageMask1(image1.size(),CV_8U);
 imageMask1(Rect(0,0,imageMask1.cols,imageMask1.rows)).setTo(255);
 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);
 cv::imshow("mask",masks[1]);
 masks[0].convertTo(masks[0],CV_8UC3,255);
 cv::imwrite("F:\\1\\998.jpg",masks[0]);
 masks[1].convertTo(masks[1],CV_8UC3,255);
 cv::imwrite("F:\\1\\999.jpg",masks[1]);
 printf("%lu\n", masks.size());
 //for(int i = 0; i < masks.size(); i++)
 //{
 //     std::cout << "MASK = "<< std::endl << " "  << masks.at(i) << std::endl << std::endl;
 // }
 cv::waitKey();
  return 0;

}

In the given documentation they given that to pass source image mask in place of third argument.So i passed a white image.I am not understanding what we should pass in place of third argument.Please help .

what are the input and output arguments?
Are there any examples or references present for this ?

In the above function belonging to stitching module,what it ouputs i.e it is given that it estimates the rotations of images .how and in which form it will output?What is rotation matrix?I want what will be there in cameras?

Can we pass descriptors of type Mat in place of this argument ?

thank you . I am implementing the function match() - stitching module

Can anyone describe each parameter in this function ? What we have to pass for ImageFeatures? Can we use Mat and for MatchesInfo?Please describe what it ouputs(i.e in which format image or vector or anything).

feather blending?

Generally so far i have seen in blenders.hpp it is given that for function feed image should of the type 8UC3 OR 16SC3 but how to use for grayscale images (1 channel)?

What actually does indices refer to in a color image ?

What are the dimensions of features matrix ?
