to ease your pain, ditch the cin
, and use a trackbar, like this:
Mat img(300,300,CV_8UC3, Scalar(200,0,0));
Mat img2(300,300,CV_8UC3, Scalar(0,0,200));
Mat des;
int blend=50;
namedWindow("Blended");
createTrackbar("blend", "Blended", &blend, 100);
while(1) {
double alpha = (double)blend / 100;
addWeighted(img, alpha, img2, 1.0 - alpha, 0, des);
imshow("img", img);
imshow("ime1", img2);
imshow("Blended", des);
