Dear Martha,

Why don't you try conventional edge-detection with liner filters ( say Sobel)? It
is already implemented in ImageJ. I am not sure how the Hough transform handles images with
degraded geometric forms (e.g. noisy images). The other thing you can try is to
threshold the images and then skeletonize them.

best regards

Subject: linear Hough transform

Hello All,

I need to detect faint linear signal (fine processes on neurons) in images.
I wanted to try using a linear Hough transform. In the listserv archives a
"Linear_Hough_Transform_.class plugin" is mentioned, but I can not find it.
Can someone tell me where it is (the source code)?  If the source code for
this plugin is not available, I wondered if someone could tell me if it
would be relatively easy to convert the Hough Circles plugin to detect
lines or if that would be a bad way to go about things.

Thanks,
Martha Narro
