creating a real blank image

Hello everyone!!!
Does anyone know how to create a blank image?
I.e. an image whose pixel values equal nothing: not zero, but nothing at all!
I want to create an image that I can add or average to any existing image without modifying it at all.
Anyone knows if this can be done?
Thanks a lot in advance.

Re: creating a real blank image

Good day Joaquim Soriano Felipe,

it's always interesting to realize special needs of colleagues!

I really don't understand what you have in mind but you may first create
a 32bit image with all values set to zero and then apply "Reciprocal"
from the IJ menu item "Process > Math". This results in an image with
all values set to NaN (not a number). Of course, "not a number" isn't
"nothing at all"...

Another approach could be based on transparency.

Best

Herbie

Hi Joaquim;

Looks quite impossible to have nothing within an image.
Finally the image is a set of values in the memory that some software shows as a image ruled by some parameters (width, height,bitdepth,etc.)
If you need to add nothing create an image fill with zeros, if you need to average two images and keep the same image at the end use two identical images.

Whatever maybe someone knows some entelechy so good luck.

That is a quite interesting wish. It reminds me to the book "The Neverending Story" from late Michael Ende. In this book the/a "nothing" spread out and still I had the problem what that could mean.

If you are able to deliver one pixel of "nothing" or even less most of us could let it spread out and fill your image (and I think uncountable numbers of problems could be solved)!

In reply to this post by Soriano.Joaquim

Sure, you could create a float image and fill it with NaN. Of course you must know yourself what to do with it...
Here is a sample plugin:

//--------------------------------------------------------------
import ij.ImagePlus;
import ij.plugin.PlugIn;
import ij.process.FloatProcessor;

public class Make_NaN_Image implements PlugIn {

public void run(String arg0) {
FloatProcessor fp = new FloatProcessor(100,100);
fp.setValue(Float.NaN);
fp.fill();
(new ImagePlus("NaN-Image", fp)).show();
}

}

Re: Display Geotiff image using imageJ

In reply to this post by Feras

Hi Feras,

ImageJ can open most TIFFs, including 16-bit (often used for global DEMS).
The only difficulty you might come across is that there are a lot of
different flavors of TIFF (e.g., some store raw and some store compressed
image data). ImageJ will probably tell you why it cannot open a TIFF - and
ArcGIS might give you options on exporting the image, so you can write out
a compatible one. Good luck!

Best wishes,

Mark

Re: Display Geotiff image using imageJ

Hi Feras,

ImageJ is open source, so you can just go find the Java code that
accesses the image data and tags in TIFF files, if you need to extract
the 'geo' part -- but if it is just a matter of opening the TIFF image for
display, switch on the macro recorder and use the File menu to open the
image. The macro code will be recorded in the window; you can copy it to
a separate text file. There are many macro examples on the ImageJ website
that will help to get you started.

Best wishes,

Mark

Benjamin Eltzner

"Rod filter" plugin.

In reply to this post by karo03

Dear list,

I would like to write a plugin that does an operation at each pixel and
takes into account only certain other pixels in the neighborhood of the
pixel.

Assume for example, I want to take the mean brightness of the pixel
itself and 5 neighbors in a straight diagonal to its upper left and 5
neighbors in a straight diagonal to its lower right. (So a rectangular
mask for the convolve() method will not do.)

Could you point me to the ImageJ API functions to accomplish this as
efficiently (as in calculation time, not developer time) as possible? If
you know a plugin that does something similar I would also be glad for a
pointer.

Best Regards,

Benjamin

Re: "Rod filter" plugin.

Hi Benjamin,

looks like you could do it with convolution:

0 0 0 0 0 0 0 0 0 0 1
0 0 0 0 0 0 0 0 0 1 0
0 0 0 0 0 0 0 0 1 0 0
0 0 0 0 0 0 0 1 0 0 0
0 0 0 0 0 0 1 0 0 0 0
0 0 0 0 0 1 0 0 0 0 0
0 0 0 0 0 0 1 0 0 0 0
0 0 0 0 0 0 0 1 0 0 0
0 0 0 0 0 0 0 0 1 0 0
0 0 0 0 0 0 0 0 0 1 0
0 0 0 0 0 0 0 0 0 0 1

But this won't be the fastest option in terms of execution time, it does a lot of unnecessary multiplications by zero.
To get it a bit faster, discard the left 4 colums of the matrix, and translate the result by 2 pixels. This will leave some edge pixels undefined, however.

For a faster code, write a PlugInFilter. Typically you would specify the CONVERT_TO_FLOAT, DOES_ALL, SNAPSHOT, SUPPORTS_MASKING, PARALLELIZE_STACKS and (for large images) PARALLELIZE_IMAGES flags.

You find a very simple PlugInFilter example at
http://rsb.info.nih.gov/ij/plugins/apply-formula/Apply_Formula.java

In your case, in the run(ip) method, take the snapshot pixels of the ImageProcessor (a float array with all pixels) as input and write to the pixels array (also float) as output. And you have to care about near-edge pixels, because some of the input pixels won't be inside the image for them.

float[] pixels = (float[])ip.getPixels();
float[] snapshotPixels = (float[])ip.getSnapshotPixels();
int width = ip.getWidth();
Rectangle roi = ip.getRoi();
for (int y=roi.y; y<roi.y + roi.height; y++) {
for (int x=roi.x; x<roi.x + roi.width; x++) {
// p points to pixel (x,y) in the arrays
// read input values as snapshot[x_input + y_input*width]
// calculate whatever you want
pixels[x + y*width] = result_of_calculation;
}
}

Re: Display Geotiff image using imageJ

In reply to this post by Mark J. Chopping

Hi Mark,I installed imageJ opensource and was able to view normal tif file. however, when I tried to view geo tiff file as coded here, I get an error as follows:
The code:ImagePlus imp = IJ.openImage("C:/localdata/output/srtm_13_02/srtm_13_02_1.tif30_200.tif"); imp.show();
The error:Unsupported BitsPerSample: 64

Thanks in advance!Feras

Re: Display Geotiff image using imageJ

Hi Feras,

Is your GeoTIFF really a 64-bit image? Seems unlikely but if so, why not
write it out as a 16-bit image, if that is an option?

However, it looks like you are tyring to view a Shuttle Radar Topography
Mission digital elevation model: what are the characteristics of the
original SRTM file? 16-bit?

Re: Display Geotiff image using imageJ

Hi Mark,Yes, I am using Shuttle Radar Topography Mission digital elevation model data to view the output of hillshades generated by uDig. At this moment I only can see the image by drag and drop ti ArcGIS.I just wonder how can I view the output using java code without using drag and drop in ArcGIS
Many thanks in advance!Feras

Hi Feras,

the SRTM files from
http://www.cgiar-csi.org/data/srtm-90m-digital-elevation-database-v4-1
are 16-bit tiffs and open nicely in ImageJ.

Re: Display Geotiff image using imageJ

Hi Michael,
I agree that the SRTM data can be viewed by imageJ java code without problems. But, the problem is after conversion to show hillshades. The only way to view the new generated tiff is through drag-drop to ArcGISAny Idea ?
ThanksFeras

Hi Feras,

the SRTM files from
http://www.cgiar-csi.org/data/srtm-90m-digital-elevation-database-v4-1
are 16-bit tiffs and open nicely in ImageJ.

A formal question re ImageJ2

In reply to this post by Soriano.Joaquim

Dear Curtis and those who are in the know,

for good reasons I need to know whether plain ImageJ2 (not Fiji with its
additional plugins) is open source in exactly the same legal sense as
plain ImageJ1?

With "plain ImageJ2" I mean the software that provides about the same
functionality as ImageJ1.

Best regards

Herbie

Like most of the SciJava software projects [1], ImageJ2 uses the Simplified
BSD License [2], one of the most popular permissive OSS licenses. It makes
only one stipulation: that derivative works retain the copyright notice,
for purposes of provenance tracking and citation.

We have been very careful to track the origin of all source code in the
projects, including dependencies, to ensure that all stated licenses are
indeed valid.

The following newly minted wiki page summarizes everything, including a
discussion of ImageJ 1.x's copyright status:

* http://imagej.net/Licensing

These pages may be informative as well:

* http://choosealicense.com/
*
https://en.wikipedia.org/wiki/Copyright_status_of_work_by_the_U.S._government

Re: A formal question re ImageJ2

Many thanks Curtis!

The <http://imagej.net/Licensing> overview is very helpful to get an
impression. However, the footnote regarding ImagJ1 is less clear but it
explains why...

In any case, the license of ImagJ1 and that of ImagJ2 are fundamentally
different.

Thanks again and best regards

Herbie

Re: A formal question re ImageJ2

Hi Herbie,

`fundamentally different' is a very vague and bold statement and as such
prone to misinterpretation by those less familiar with the topic. I
therefore feel urged to clarify:

The only difference between the licenses of ImageJ1 and ImageJ2 is that
you cannot claim that you wrote ImageJ2, but you can claim that you
wrote ImageJ1.

With both licenses you can use, modify, give away, sell, wrap the
licensed code, parts of it, or binary distributions of it, in open
source as well as closed source commercial projects. No constraints.

The exact difference between the two licenses is that ImageJ2 requires
you to retain that copyright notice and make this information accessible
for those consuming your derived work, i.e. give minimal virtual kudos
to those who developed ImageJ2. I, personally, would spare
`fundamental' for something more `fundamental'.

Best,
Stephan
