Parameters
pDeconvLR
Pointer to the LR deconvolution state structure.
pKernel
Pointer to the kernel array.
kernelSize
Size of the kernel.
maxRoi
Maximum size of the image ROI, in pixels.
threshold
Value of the threshold level (to exclude dividing by zero).
Description
This function initializes the LR deconvolution state structure that is used by the
ippiDeconvLR
 function to perform LR deconvolution of the source image. Before using the
ippiDeconvLRInit
 function, compute the size of the structure using the
ippiDeconvLRGetSize
 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
  • kernelSize
     is greater than
    maxRoi.height
     or
    maxRoi.width
  • maxRoi.height
     or
    maxRoi.width
     is less than, or equal to zero
ippStsBadArgErr
Indicates an error when
threshold
 is less than, or equal to 0.
