Create Your Own Deblurring Functions
All the toolbox deblurring functions perform deconvolution in the frequency domain,
where the process becomes a simple matrix multiplication. To work in the frequency
domain, the deblurring functions must convert the PSF you provide into an optical
transfer function (OTF), using the psf2otf
function. The toolbox also provides a function to convert an OTF
into a PSF, otf2psf
. The toolbox makes these
functions available in case you want to create your own deblurring functions.
To aid this conversion between PSFs and OTFs, use the padding function padarray
.
