DeconvFFTInit

Initializes the FFT deconvolution state structure.

Syntax

IppStatus ippiDeconvFFTInit_32f_C1R(IppiDeconvFFTState_32f_C1R* pDeconvFFTState, const Ipp32f* pKernel, int kernelSize, int FFTorder, Ipp32f threshold);

IppStatus ippiDeconvFFTInit_32f_C3R(IppiDeconvFFTState_32f_C3R* pDeconvFFTState, const Ipp32f* pKernel, int kernelSize, int FFTorder, Ipp32f threshold);

Parameters

pDeconvFFTState	Pointer to the FFT deconvolution state structure.
pKernel	Pointer to the kernel array.
kernelSize	Size of the kernel.
FFTorder	Order of the created FFT state structure.
threshold	Value of the threshold level (to exclude dividing by zero).

Description

This function initializes the FFT deconvolution state structure that is used by the ippiDeconvFFT function to perform deconvolution of the source image using FFT. Before using the ippiDeconvFFTInit function, compute the size of the structure using the ippiDeconvFFTGetSize function.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error when any of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when kernelSize is less than, or equal to 0; or if kernelSize is greater than 2^FFTorder.
ippStsBadArgErr	Indicates an error when threshold is less than, or equal to 0.
