void saveImage	(	const string &	fileName,
		IplImage *	img
	)

Save an image under a certain file name.

Parameters:

	fileName	name of the image file
	img	image to save

void drawImgInfo	(	const vector< ImgInfo > &	vImgInfo,
		const CvMat *	HGlobal,
		const vector< CvMat * > &	HPanorama,
		IplImage *	img,
		Match &	match,
		bool	doEdge
	)

Draws pixels of value the number of the image.

Parameters:

	vImgInfo	vector containing info about the images
	HGlobal	global homography to apply so that an image is at the center
	HPanorama	vector of homographies applied to the images
	img	image to which the info is written
	match	contains all the information concerning matches
	doEdge	flag indicating if white is drawn or the value of the pixel
