Gaussian downsampling with ImageJ on-board tools

[Stephan Saalfeld]

Hi all,

I wrote a little Javascript for Gaussian downsampling of an image which
is of particular importance when scaling down a lot.  ImageJ has
everything on-board to do this and Javascript is a beautiful language ;)

Find the script and documentation here:

Best regards,

I just tried for some preview images on a homepage...really nice

All the best,
Steffi

Hi Gabriel,

no no, I just use it to create thumbnails. And there it is really important
to use a proper downsampling as you decrease the image size by at least one
order of magnitude. Other interpolation schemes are not very good for that,
as they just ignore most of the input pixel.
