pfftdeconvolution
Performs deconvolution of image by kernel.
Synopsis
pfftdeconvolution [im_in1|-] [im_in2|-] [im_out|-]
Description
pfftdeconvolution performs a deconvolution the input image im_in1
with the kernel given in the input image im_in2.
The size of the kernel image im_in2 must be lower or equal
than the input image im_in1.
The deconvolution uses the frequency domain.
It consists in a complex division of
the Fourier transform of the two input images:
- imi=fft(im_in) / fft(im_in2)
- im_out=iift(imi);
where / is the complex division.
Inputs
- im_in1: a 2D image.
- im_in2: a 2D image (same type as im_in1 and a size lower or equal to im_in1).
Outputs
- im_out: a float image of the same size as the input image im_in1.
Result
Returns SUCCESS or FAILURE.
