create_table()

LUTable * create_table	(	int	ncol,
		int	sizeT
	)

Parameters

ncol
sizeT

Returns

int 0

kill_table()

int kill_table

(

LUTable *

lut

)

weigh_radon_transf()

int weigh_radon_transf	(	Bimage *	p,
		Bimage *	pmask
	)

Weighs a radon transform with a mask.

Parameters

*p	radon transform.
*pmask	mask calculated for the radon transform.

Returns

int 0

The mask is searched for the minimum value to assess completeness.
Each value in the mask above a threshold is inverted (the weight to be applied).
Values below the threshold is set to zero.
The threshold is set to 0.9.

		Bimage *	prec,
		int	angolo,
		float	csi,
		float	eta,
		Bimage *	pmask,
		LUTable *	lut,
		float *	priga
	)

Parameters

*p
*prec
angolo	angle index
csi
eta
*pmask
*lut
*priga

Returns

int 0
