2013-06-18 04:59:17 -0500 answered a question Resizing Image

you can resize your image by using this code,

double ra=1.0; int newWidth; int newHeight; int main() { Mat size= imread("your filename"; double ff=700; // this will change the image resolution to 700X700 if (size.cols > size.rows) { ra = ff / size.cols; } else { ra = ff / size.rows; } newWidth = (int)(size.cols * ra); newHeight = (int)(size.rows * ra); cv::resize(size,size,cv::Size(newWidth,newHeight)); imshow(size);

Hello all, I am using grabcut sample code from opencv as a part of my project... the final image which i am getting after using that sample code contain black background... according to me, it is because of the mask....?? i have tried everything to change the background to white or transparent...

Hello all, i am working on a project, for which i am using grabcut sample code. it is working perfectly... But my question is, how can i save the final image after the required iterations... so that i can use that image for my further processing.... Waiting for replies...
