Member Enumeration Documentation

◆ Mode

enum ImFusion::GlNoiseFilter::Mode

Noise model to use for computation.

Enumerator

PHYSICAL_POISSON

Assumes that the image values represent integer counts for physically plausible simulation of poisson noise.

Float images need to be prepared (i.e. normalized, and scale!=1, shift!=0). The parameters are intrinsically defined.

Member Function Documentation

◆ setKernelSize()

bool ImFusion::GlNoiseFilter::setKernelSize	(	int	,
		double	)

overridevirtual

Reimplemented from ImFusion::GlFilter.

◆ compute() [1/2]

void ImFusion::GlNoiseFilter::compute	(	const GlImage &	imgIn,
		GlImage &	imgOut )

overridevirtual

Execute the filter on the image.

Implements ImFusion::GlFilter.

◆ compute() [2/2]

void ImFusion::GlNoiseFilter::compute	(	SharedImage &	imgIn,
		SharedImage &	imgOut )

Reimplemented from ImFusion::GlFilter.

◆ good()

bool ImFusion::GlNoiseFilter::good ( ) const

overridevirtual

Return true if the filter can be used, in particular if the shaders are available.

Implements ImFusion::GlFilter.
