ImageSet<T> buildPyrRetinexLog	(	const Image< T > &	L,
		const size_t	depth,
		const int	niter,
		const Rectangle &	outrect
	)			[inline]

Build a retinex pyramid of the given depth using niter iterations.

The input is expected to be in log scale, and the output will also be in log scale.

This implementation is based on "McCann99" algorithm described in

Brian Funt, Florian Ciurea, and John McCann "Retinex in Matlab," Proceedings of the IS&T/SID Eighth Color Imaging Conference: Color Science, Systems and Applications, 2000, pp 112-121
