Inheritance diagram for stira::deconvolve::IterativeDeconvolve:

Public Member Functions
void	SetLambda (double lambda)
	sets regularization parameter lambda

double	GetLambda ()
	gets regularization parameter lambda

void	SetStepSize (double stepSize)
	sets step size

double	GetStepSize ()
	gets step size

int	GetMaximumNrOfIterations ()
	gets the maximum number of iterations

void	SetMaximumNrOfIterations (int nrIter)
	sets the maximum number of iterations More...

Public Member Functions inherited from stira::deconvolve::DeconvolveMaster
virtual bool	Run ()=0
	Runs the actual restoration algorithm After completion, get the result with GetRestoredImage()

Image *	GetDegradedImage ()
	Gets the degraded input image.

void	SetDegradedImage (Image *pDegradedImage)
	sets the degraded image to restore More...

Image *	GetPSF ()
	gets the Point Spread Function (PSF) The PSF is a model of the blur; it is how every single point is imaged in the degraded image. For an ideal image, it would be a delta function; in reality, it is mostly a certain spot.

void	SetPSF (Image *pPSF)
	sets the Point Spread Function (PSF) More...

Image *	GetRestoredImage ()
	gets the result after running the deconvolution

void	SetSigmaNoise (double sigma)
	sets the noise level More...

double	GetSigmaNoise ()
	gets the noise level

virtual bool	IsReadyToRun ()=0
	checks if all conditions are fulfilled for this deconvolution method

void	Initialize (int maxNrOfIterations)
	initializes all data structures for deconvolution

bool	PrepareCurrentGrids ()
