Edit Filter

[Klughammer GmbH]

Hi,

I am looking for a 5x5 or 7x7 HighGauss Filter.

I could edit it by myself. Is there a possibility to edit filters
in ImageJ?

Regards

Is Process>Filters>Convolve what you're wanting to edit filters?

Anna,

I'm not sure what a HighGauss Filter is, but you can compute a Gaussian
filter with Gaussian PSF 3D, which is linked from the page Convolve 3D on my
site: http://www.optinav.com/ImageJplugins/Convolve_3D.htm   Run Gaussian
PSF 3D and choose, for example, 7,7,1 for the height, width, and number of
slices, and enter 1 for all of the other inputs.  (You may prefer different
widths for the 5th and 6th inputs.) The resulting Gaussian image can be
saved as a text file (File/Save As/Text Image...) and used as a filter
kernel by pasting it into the window for Process/Filters/Convolve....  There
are a number of other options for convolution, some of which are specific to
32-bit real images.

You can achieve something similar with Process/Filters/Gaussian Blur..., but
you won't have as much contol.
