Java code for Process-> Find Edge

[donny008]

Hello

I am excited about using the command  Process-> Find Edge for analysing my
images. However I believe I would like to add on to certain aspects on this
particular feature. I tried to figure out the code from the imagej website
but i was  not able to. Could someone please guide where i could find the
java source code for this feature.

Please help

regards

i think its in: ij.process.ByteProcessor

Its in in the "filter()" method


You do have the source code right?

You can find it here:

http://pacific.mpi-cbg.de/cgi-bin/gitweb.cgi?p=ImageJA.git;a=blob;f=ij/process/ImageProcessor.java;hb=refs/heads/master#l1283

(The filter() method is abstract in the ImageProcessor class, and is
implemented in each subclass exlicitely.)

For what it's worth, I found it by starting Fiji's Script Editor (in a
Fiji built from source including ImageJ), calling Tools>Open .java file
for menu item..., and following a few calls through Tools>Open .java file
for class...

Hth,

Thankyou so much

indeed i have the code for the sobel operator now. What was more interesting
to me is how the results of the sobel image are displayed onto the original
image but i am not able to find that part. I guess it should something like
draw() or show(). Is that right. Does such a code exist ?

thanks for the help in advance

The filter() method replaces the pixels; it does not do an overlay. If you
want to do that, you might want to play with the setOverlay() method of
ImagePlus.
