OpenCV: convert Scalar to different color space

Question

I am using a Scalar to define the color of a rectangle I am drawing with OpenCV:

rectangle(imgOriginal, Point(0, 0), Point(25, 50),         


        

Answer 1

This worked for me,

Mat rgb;
Mat hsv(1, 1, CV_8UC3, Scalar(224, 224, 160));

cvtColor(hsv, rgb, CV_HSV2BGR);
Scalar rgb = Scalar((int)rgb.at(0, 0)[0],(int)rgb.at(0, 0)[0],(int)rgb.at(0, 0)[0])
