Dear Rabih,

I suggest you read the ImageJ user guide at
http://rsb.info.nih.gov/ij/docs/guide/146.html

People on this list will answer one, maybe two very basic questions covered
in the manual, but not a lot more than that, and certainly not if you send
them multiple times.

Best Regards,

Christophe

Hi rabih,

You can't use Set Scale if you don't have a reference to use.

What kind of images are you using? If they are from a microscope, then you can use a micrometer slide to take a reference image and then use those images to calibrate - set scale.

Kind regards,

Jacqui

As they all said... There is no magic, if the information is not in the image... If you can reproduce exactly how the image was taken you could obtain a calibration ....
