DeconvFFTInit
Initializes the FFT deconvolution state structure.
Syntax
IppStatus ippiDeconvFFTInit_32f_C1R(IppiDeconvFFTState_32f_C1R* pDeconvFFTState, const Ipp32f* pKernel, int kernelSize, int FFTorder, Ipp32f threshold);
IppStatus ippiDeconvFFTInit_32f_C3R(IppiDeconvFFTState_32f_C3R* pDeconvFFTState, const Ipp32f* pKernel, int kernelSize, int FFTorder, Ipp32f threshold);

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 2FFTorder. |
ippStsBadArgErr |
Indicates an error when threshold is less than, or equal to 0. |
