normalize_rgb()

void normalize_rgb	(	RGB *	rgb,
		u_long	length,
		double	scale,
		BOOL	mono
	)

Multiply the pixels by a scalar.

Parameters

rgb	The sarray of rgb value to normalize
length	The array length
scale	The scale by wich the pixels will be multiplied. If 0, they will be multiplied by 1/max(rgb)

This function is used for dark frames or flat fields, to normalize the stacking result according to its use (ie: dark frame stack shall be a mean value, and flat fields stack shall have its maximum equals to one).

quality()

static double quality ( SPECTRUM  spectrum, u_short  width, u_short  height, u_short  down, u_short  up  )
