Constructor & Destructor Documentation

cuSincOverSamplerR2R()

cuSincOverSamplerR2R::cuSincOverSamplerR2R	(	const int	i_covs_,
		cudaStream_t	stream_ )

cuSincOverSamplerR2R constructor

Parameters

i_covs	oversampling factor
stream	cuda stream

Member Function Documentation

execute()

void cuSincOverSamplerR2R::execute	(	cuArrays< float > *	imagesIn,
		cuArrays< float > *	imagesOut,
		cuArrays< int2 > *	centerShift,
		int	rawOversamplingFactor )

Execute sinc interpolation.

Parameters

[in]	imagesIn	input images
[out]	imagesOut	output images
[in]	centerShift	the shift of interpolation center
[in]	rawOversamplingFactor	the multiplier of the centerShift

Note

rawOversamplingFactor is for the centerShift, not the signal oversampling factor
