Member Function Documentation

vector< Box2D3D > people::Faces::detectAllFaces	(	cv::Mat &	image,
		double	threshold,
		cv::Mat &	disparity_image,
		image_geometry::StereoCameraModel *	cam_model
	)

Detect all faces in an image.

Input:

Parameters:

	image	The image in which to detect faces.
	haar_classifier_filename	Path to the xml file containing the trained haar classifier cascade.
	threshold	Detection threshold. Currently unused.
	disparity_image	Image of disparities (from stereo).
	cam_model	The camera model used to convert 2D points to 3D points. Output: A vector of Box2D3Ds containing the bounding boxes around found faces in 2D and 3D.
