Surface coverage questions

[Adam Hughes]

Hi,

I use the analyze particles feature all the time in imagej, but I'd like to
be able to quantify coverage density over my picture surface.  For example,
create a density map or something that would say "hey the top left quadrant
of the picture has x density, while the bottom right has y density".  Do
you guys know of any plugins that work with the analyze particles
routines/output to address these kinds of problems?

Just curious where to start.

Thanks.

Hi,
I do not know a plugin for that purpose, but I am wondering whether
this here could be a starting point:
http://fiji.sc/cgi-bin/gitweb.cgi?p=fiji.git&a=blob&f=src-plugins/VIB_/src/main/java/util/Histogram_2D.java
If you just want to have a simple information like what you describe
(density in a quadrant), you could use Analyze Particles to get a
point selection and then count the points in whatever bins you want to
have in your image.
Best regards,
Volker

Ok thanks, I will try this and let you guys know if I am able to implement
it.

I can run multiple instances of ImageJ on a Windows XP 64 machine.  
But I have another machine with Windows 7 and it won't open multiple instances of ImageJ.
Is there a setting or something I'm missing?
Thanks,
Frank

Hi Franklin,

Most likely, the difference is not so much the Windows version but the
ImageJ version. Starting ImageJ with the option "-port0" will force it to
start a new instance.

Ciao,
Johannes

Hi Frank,

Check under Edit > Options > Misc. On your windows 7 systems "Run single instance listener" is most likely selected. Deselect it and you can open multiple instances of Image.
