void CalibratedPyramid::Init	(	const CalibratedImage< StorageType > &	image,
		const unsigned	pyramid_size = `2`,
		const double	rescale_factor = `4.0`
	)

initialization with original image, total number of images in the pyramid and a rescale factor.

A rescale factor of 4.0 means the the image at pyramid level[i] has a quarter of the border lengths of the image at pyramid level[i-1]. A rescale factor of 2.0 for example represent a classical Gaussian pyramid.
