Parameters

nChannels: Number of channels in the image. Possible values are 1 or 3.
kernelSize: Size of the kernel.
FFTorder: Order of the created FFT state structure.
pSize: Pointer to the size of the IppiDeconvFFTState_32f_C1R or IppiDeconvFFTState_32f_C3R structure, in bytes.

Description

This function computes the fast Fourier transform (FFT) deconvolution state structure size that is required to initialize the structure with the

function. This structure is used by the

function, which performs deconvolution of the source image using FFT.

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.
ippStsNumChannelsErr: Indicates an error when
nChannels
has an illegal value.
ippStsSizeErr: Indicates an error when
kernelSize
is less than, or equal to 0; or if
kernelSize
is greater than 2^FFTorder.
