	camera = webcam; % Connect to the camera
	videoFrame = snapshot(camera);
	% Create a cascade detector object.
	faceDetector = vision.CascadeObjectDetector();
	bbox = step(faceDetector, videoFrame);
	% Draw the returned bounding box around the detected face.
	videoFrame = insertShape(videoFrame, 'Rectangle', bbox);
	figure; imshow(videoFrame); title('Detected face');
	% Convert the first box into a list of 4 points
	% This is needed to be able to visualize the rotation of the object.
	bboxPoints = bbox2points(bbox(1, :));
	clear camera
