Antwort: Sub-Pixel Edge detection plugin?

Hi Calvin,

did you really search thoroughly? Look there, they even seem to have a
ImageJ plugin, but it´s not (yet) public!? Maybe you can contact them?

Hello to all,
I am doing an intensive project over the next couple weeks that is
concerned
with computer vision dimensional guaging. I was planning to use ImageJ for
the image editing software as there are possibilities of needing to write a
plugin to gather and store data about a picture.

But what I really need is a plugin that can find edges to a sub-pixel
standard. All I will be doing is finding the diameter of a circular object
to a sub-pixel standard. Does any one knnow of a plugin that does this. I
would gladly make one but this is an area that I know little about and dont
have time to do a lot of background learning. So if anyone could even let
me
know the steps in the procedure of sub-pixel edge detection and the names
of
some algorithms or processes used for them it would be a tremendous help, I
have searched the internet thouroughly and there are no real clear
insrtuctions for what I'm doing that doesnt cost money. I am sorry to
bother
you all but time is really an issue so if anyone could give me a shove in
the right direction I would be most grateful.
Thank you for you time, and I wish you all luck on your current work
projects.

Calvin Slope
