void HandDetector::customValues ( cv::VideoCapture cap )

Obtains the custom HSV skin range.

Shows and image with information, then shows the calibration image and from the information obtained calculates the HSV skin color range. Finally, it calls the calibrationLoop function

    int delay=24;

    cv::Mat custom=cv::imread("../img/custom.png");
