Have you looked into the Hough linear transform? It can be tuned to the
crack width. Look on the Plugins page of the ImageJ site and follow the
link, in the Links to External Sites section, to Wilhelm Burger and Mark
Burge's page.

Subject: Alternative to threshold
Hello!
I'm trying to separate the cracks out (picture) as precise as possible.
Grains on the background make ordinary threshold tricky. On other images
that I have direction of cracks and grains could be the same, so Sobel like
operators dont fit unfortunately.
Is it possible to provide labeling or segmenting according to cracks
intensity change (cracks have at least sharp slope in the intensity change
(plot profile))?
Could you suggest me any plugin or algorithm where I can set this kind of
criteria for the segmentation.
Thank you!
