OpenCV detect color Automatically

Question

Is there a possible way to make Color Blob Detection automatically detect a specified color without pressing it ?

Ex I'll just specify what range of color is I want then it would automatically detect the color with the same range.

What do you mean by pressing it. Also: define color-range! — sascha

Color blob detection works by pressing the screen and detect same color of what was being pressed. — Shulz

You probably need to use cv::inRange and define your range of colors as (r1,g1,b1) to (r2,g2,b2). E.g.:

cv::inRange(input, cv::Scalar(0,140,0), cv::Scalar(160,255, 160), output);
