DeconvLR

Performs LR deconvolution of an image.

Syntax

IppStatus ippiDeconvLR_32f_C1R(const Ipp32f* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize roiSize, int numIter, IppiDeconvLR_32f_C1R* pDeconvLR);

IppStatus ippiDeconvLR_32f_C3R(const Ipp32f* pSrc, int srcStep, Ipp32f* pDst, int dstStep, IppiSize roiSize, int numIter, IppiDeconvLR_32f_C3R* pDeconvLR);

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.
numIter	Number of algorithm iterations.
pDeconvLR	Pointer to the LR deconvolution state structure.

Description

The function ippiDeconvLR 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 the Lucy-Richardson algorithm with parameters specified in the state structure pDeconvLR and stores results to the destination image pDst. The Lucy-Richardson deconvolution state structure must be initialized by calling the function ippiDeconvLRInitAlloc 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.
ippStsSizeErr	Indicates an error condition if roi.width or roi.height is less than or equal to 0, or if roi.width is greater than (maxRoi.width - kernelSize), or roi.height is greater than (maxRoi.height - kernelSize).
ippStsStepErr	Indicates an error condition if srcStep or dstStep is less than `roiSize.width * <pixelSize>`.
ippStsNotEvenStepErr	Indicates an error condition if steps for floating-point images are not divisible by 4.
ippStsBadArgErr	Indicates an error condition if numIter is less than or equal to 0.
