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);
}
