	Overloaded initializer for the class. Must provide the distortion parameters and image size.
int	libclass_lensundistort::UndistortImage (const IplImage *src, IplImage *dst)
	The actual undistortion method. Undistorts the image using the undistortion parameters given in the constructor. During initialization a LUT is created for the undistortion procedure. This function uses this LUT to perform fast undistortion.

int libclass_lensundistort::UndistortImage	(	const IplImage *	src,
		IplImage *	dst
	)			[inherited]

The actual undistortion method. Undistorts the image using the undistortion parameters given in the constructor. During initialization a LUT is created for the undistortion procedure. This function uses this LUT to perform fast undistortion.

Parameters:

	src	The imput image
	dst	The output image
