Isolines with ImageJ

[Juan Francisco-2]

Dear all:

pls, how it´s possible to display isolines (line connecting points with the same gray value) on a image opened with ImageJ?

On the other hand, how its possible to build a normalizated image to its maximun value with ImageJ?. I mean: for a give image, recalculate this image so that the maximun gray value be 100 and the remainning re-escalated.

 

Thanks a lot!!!

Hi,

for the isolines, try the Contour_Plotter plugin,  
http://rsb.info.nih.gov/ij/plugins/contour-plotter.html.
To normalize an image, divide all the pixels by the maximum  
(Process>Math>Divide) and multiply by 100 (Process>Math>Multiply).

cheers,

Arnaud

Generally spe
Juan,
you can do this with the contour plotter plugin.

Generally speaking you can easily find many answers with the search tools available at
http://rsb.info.nih.gov/ij/search.html

or why not directly in the online manual at
http://rsb.info.nih.gov/ij/docs/index.html

You can also search this mailing list archive at
