Re: IMAGEJ Digest - 9 Feb 2009 to 10 Feb 2009 (#2009-40)

Kordowska, Jolanta (DPH)
Hi All,

Iam new to ImageJ and may be you have some advice to me.

I am searching through ImageJ and try to find the way of converting dots into value, further set threshold and all values above threshold convert into "1" s, and below threshold into "0"s (into binary numbers I could export to excel).

My initial template is an image in jpeg with mesh of 45 by 45 gray/black dots of different intensity. At the end what I need are rows of each dot translated into 0 or 1.

Can somebody out there please give me some insights or suggestions?
Thank you
regards

Jolanta Kordowska

Hi John,

it means that the ShiftDialog.class is missing from the ImageJ\plugins
directory. You may accidentally deleted it, or the class file has not bee=
n
created for some reasons. You should try to recompile the plugin, and che=
ck if
ShiftDialog.class exists. And it's also a good idea to download the newes=

Subject: File Conversion bug and Batch Converter

  Hello again listmates,

If I try to convert 16bit color images into 8bit grayscale by doing
"image>type>8bit" I get an RGB stack instead.

The way I found around that is doing "image, color, stack to rgb"
followed by "image, type, 8bit".

Shouldn't I be able to convert directly? Maybe its a bug...

Also, I tried to apply the batch converter plugin to convert all the
files from a folder to 8bit-TIFF and this is what I get:

Subject: uncertainty measurement

Hi all,
 
I am trying to calculate the uncertainty associated to particles analisys
and in particular feret data.
I start with SEM micrograph of particles deposited on filter membrane.
Micrographs are taken at 25000x.
At this magnification 1 pixel is equal to 14.7 nm.
Selecting the threshold value can be a great source of errors in measurement
data, and increase with smaller particles.
Without a granulometric standard it is difficyult to estimate some kind of
uncertainty on these data.
I was wondering about how to have the highest accurate threshold possible.
One option I am consdering could be to take a point-to-point manual
measurement with teh scaler tool of teh microscope, on a particle observed
at higher mag than 25000, for ex. 250000x (at this mag 1 px is equal to
1.47nm) and then re-process the same particle taken this time at working mag
(25000x)with IJ  and compare measurement.
do you think could be a possible method to estimate uncertainty? has ever
anyone been involved in calculation like this ?

thanks in advance..
Lxq

Subject: Re: Color Transformation to HSI

Hi Eva,

We need more detail to help. What exact commands or plugins did you use? What versions of ImageJ and any plugins?
My ImageJ has commands for RGB to HSB, not HSI. (E.g.: menu command Image->Type->HSB Stack)

Part of the problem may be that these color models are not well standardized.  See for example the article at
http://en.wikipedia.org/wiki/HSI_color_space
So Metamorph may be using a different definition of HSI than the ImageJ plugin.

I'm new to Image J & I am trying to transform a color image into HSI. The
output looks different than an image/aquisition program, Metamorph, that I
was using. Looks like the Intensity image is actually the Hue or
Saturation image. Any suggestions?

Subject: Re: 12- and 14-bit PNGs in imageJ

I used imagemagick's "convert" command to convert one of these PNGs to
TIFF.  The resulting TIFF has the wrong values -- whether read by ImageJ or
IDL.  I also read in one of the problematic PNGs with IDL, then saved the
resulting (correct) image array to a new PNG.  ImageJ reads the correct
values from this new file.

I conclude that the problem lies with the original PNG image file, which
apparently gives inconsistent results among image readers/viewers; I will
investigate further.

Thanks,
Nathaniel

The Image>Type>8-bit command converts 16-bit composite color images  
(e.g., 48-bit RGB TIFFs) into 8-bit composite color images. You can use  
Image>Type>RGB Color followed by Image>Type>8-bit to convert a  
composite color image into an 8-bit grayscale image.

There is an updated version of the Batch_Converter plugin at

    http://rsb.info.nih.gov/ij/plugins/batch-converter.html

Typically, this error occurs when reading from a stream (which is the
result of opening a URL) but trying to go back to the beginning somewhere
in the middle.

I do not have any experience with the DICOM format, but I imagine that you
have that problem here, and that you need the file locally.  Or you need
to inspect the source (you did not mention which plugin, if any, you use
to open the files) to find out where it tries to "seek" (that is "going
back in a file" is called in computer speak).

It would be helpful if you described in just a tiny little bit more detail
what exactly is happening.  Nothing?  Does a window pop up with a message?  
What does the Console (/Applications/Utilities/Console) say?  What version
of Java3D do you have?  Does Fiji's 3D viewer work?

So is this expected behavior? It still bothers me it works with some dicom
files and not others. I do not have access to the file locally as i am using
imagej in an applet to view dicom files over the web (which imagej has to
import from a exposed URL).

I am not using any plugins. I am only using ij.jar. I am not sure i have the
experience necessary to debug through the ImageJ code, but i can try (if i
can get the it loaded in eclipse somehow).

It's pretty easy to debur in Eclipse actually. Check the tutorial of Mica
Kimo Johnson :
http://www.cs.dartmouth.edu/~kimo/blog/computer/imagej_eclipse.html

To debug a plugin, just load the java file into the ImageJ project you made,
and off you go.

I had Java3D 1.3 running but following the instructions here:
