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
This function 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 DeconvLRInit 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.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
