bool FaceRecognizerNode::determine3DFaceCoordinates	(	cv::Mat &	depth_image,
		int	center2Dx,
		int	center2Dy,
		geometry_msgs::Point &	center3D,
		int	search_radius
	)		`[protected]`

Computes the 3D coordinate of a detected face.

Parameters:

depth_image	Coordinate image in format CV32FC3
center2Dx	Image x-coordinate of the center of the detected face
center2Dy	Image y-coordinate of the center of the detected face
center3D	(x,y,z) coordinates of the face's center point
search_radius	Radius of pixel neighborhood which is searched for valid 3D coordinates.
