how to deconvolute an image when the line spread function is known

[mkdieric]

I want to deblur images with a custom filter. Therefore I took images of a sharp edge, which gives me the line spread function (and so also the point spread function)
It must be possible to derive a deconvolution kernel from this, but I don't know how.
Or should I do it in Fourierspace?
Thanks in advance!

I would think that the best way to do this is to use a deconvolution matrix. You can find out how to calculate the matrix in most vision books. There is a general formula.
