Member Function Documentation

unsigned long FaceDetector::detectColorFaces	(	std::vector< cv::Mat > &	heads_color_images,
		const std::vector< cv::Mat > &	heads_depth_images,
		std::vector< std::vector< cv::Rect > > &	face_coordinates
	)		`[virtual]`

Function to detect the faces on color image The function detects the faces in an given image

Parameters:

heads_color_images	Color images of the regions that supposedly contain a head
heads_depth_images	Depth images of the regions that supposedly contain a head
face_coordinates	Vector of same size as heads_color_images, each entry becomes filled with another vector with the coordinates of detected faces in color image, i.e. outer index corresponds with index of heads_color_images

Returns:: Return code
