C++ (Cpp) linear_to_sRGB Exemples

Exemple #1

Fichier : Kinect2_grabber.cpp Projet : timtianyang/PCL_region_growing

BYTE pcl::Kinect2Grabber::RGBToGreyScale(BYTE r, BYTE g, BYTE b){
	double R_linear = sRBG_to_linear(r / 255.0);
	double G_linear = sRBG_to_linear(g / 255.0);
	double B_linear = sRBG_to_linear(b / 255.0);
	double gray_linear = 0.2126*R_linear + 0.7152*G_linear + 0.0722*B_linear;
	return round(linear_to_sRGB(gray_linear) * 255);
