Hello Friends,

I want to create a mask image and i want to segment it with trimap. and put that mask image on the original image and segment it F & B image. actually i am trying Gracut where i need to create a mask image and segment it and apply it on the original image. Below is my source code and have got result but it is not according to the exact result. Please guide me with the source code to create mask image and put that on original image. YOur kind help will be highly appreciated.

Thank you in advance. Joystna

    return -1;
}

// define bounding rectangle

  cv::Rect rectangle(20,35,image.cols-40,image.rows-70);

    cv::GC_INIT_WITH_RECT); // use rectangle
// Get the pixels marked as likely foreground

// Generate output image
cv::Mat foreground(image.size(),CV_8UC3,cv::Scalar(255,255,255));
image.copyTo(foreground,result); // bg pixels not copied


// draw rectangle on original image
cv::rectangle(image, rectangle, cv::Scalar(255,0,0),5);

cv::imshow("Image",image);

// display result
cv::namedWindow("Segmented Image");
cv::imshow("Segmented Image",foreground);

hello below is my source code but it is not according to exact result because I am not using the mask image . Can anyone help me mask image source it will be highly appreciated.

include <opencv2/highgui/highgui.hpp>

include <opencv2/imgproc/imgproc.hpp>

if(! image.data ) // Check for invalid input
{
    cout <<  "Could not open or find the image" << std::endl ;
    return -1;
}

// define bounding rectangle

// int border = 50; // int border2 = border + border; //cv::Rect rectangle(border,border,image.cols-border2,image.rows-border2); cv::Rect rectangle(20,35,imag
