Hi,
I have an image volume I'd like to convolve with a Gaussian function, and I
have a particular value for sigma that I need to use.
I'm using the Gaussian resampling filter to do this, and it seems to work well;
however, the editable parameters for this filter are not well defined - in
particular, the "splat radius" , the "Gaussian exponential factor", and the
"scale factor".
Suppose my sampling volume is 56x116x39 voxels, and the voxel dimensions are
x=y=z=1mm. If I want to blur the image with a Gaussian point spread function
of sigma=1.5mm, what would I enter for "splat radius", "exponential factor",
and "scale factor"?
Any help would be most appreciated!
Best,
Luke
