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.
