DeconvFFT

Performs FFT deconvolution of an image.

Syntax

IppStatus ippiDeconvFFT_32f_C1R(const Ipp32f* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize roiSize, IppiDeconvFFTState_32f_C1R* pDeconvFFTState);

IppStatus ippiDeconvFFT_32f_C3R(const Ipp32f* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize roiSize, IppiDeconvFFTState_32f_C3R* pDeconvFFTState);

Parameters

pSrc	Pointer to the source image ROI.
srcStep	Distance in bytes between starts of consecutive lines in the source image.
pDst	Pointer to the destination image ROI.
dstStep	Distance in bytes between starts of consecutive lines in the destination image.
roiSize	Size of the source and destination image ROI.
pDeconvFFTState	Pointer to the FFT deconvolution state structure.

Description

The function ippiDeconvFFT is declared in the ippi.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function performs deconvolution of the source image pSrc using FFT with parameters specified in the FFT deconvolution state structure pDeconvFFTState and stores results to the destination image pDst. The FFT deconvolution state structure must be initialized by calling the function ippiDeconvFFTInitAlloc beforehand.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if one of the specified pointers is NULL.
