resolving subpixel resolution for complex human-like vision?

[Michael Cammer]

Given the recent discussion of resolving sub-pixel resolution, I thought
maybe the time was right to post the following question.  We've been
amassing a database of satellite/aerial images of Iraq pre-invasion from
scanning newspapers and magazines and from various sources on the
Internet.  Now we'd like to use ImageJ to automatically do feature
recognition to hunt for WMDs, maybe even to vindicate the intelligence
community.  Last week there was discussion of obtaining sub-pixel
resolution by zooming up images 8X or more.  If we zoomed up high enough,
could we even resolve microbes that might signify a bioterrorism program?
There seem to be a number of nifty plugins out there for automated feature
recognition.  Any help appreciated.

Interpolation does not create information. When the resolution of an image
is increased by whatever interpolation scheme there is always the assumption
that the original signal was band-limited, including the optimal sinc
interpolator. If no anti-aliasing filter was used, stair-casing artifact
will be present and possibly some other artifacts. In other words, if an
object is smaller than a pixel (roughly), any information about that object
is gone forever. You can zoom 1000x, nothing is going to show up (unlike in
Hollywood movies).

        The only solution is to bring to the interpolation scheme some a
priori information, and that is very specific of course to the application.
Now, if you zoom 100x a satellite image whose original resolution was 100m
and you stare at the picture for an hour trying to detect a truck, I am sure
you will find one because your brain is going to pour a priori information
in your analysis. However, someone trying to find a building will also find
one... If you take a picture that is all black (0) and one pixel has a value
of 1. If you know that a microbe should have an intensity of 100, and there
is no other possibility other than "microbe"/"no microbe", then you can
argue safely that somewhere in you pixel with intensity 1, there is a
microbe 100 times smaller than the pixel. Unfortunately, such assumptions in
real life are seldom possible.

        Some non-linear diffusion methods can be applied to restore edges
while reducing noise. For example see works from Gilboa et al. (TIP,
11(7):689-703), or reduce partial volume effect
(http://www.hindawi.com/GetArticle.aspx?pii=S168741880692092X). If you are
interested I can give you more references.

I love your work.

Does ImageJ have a "find the suspect in the victim's iris reflection
from the accidental onlooker's holiday snap" plugin yet?

If not, why not?  I saw it on CSI the other night... it must be possible.

Please could you write me a plugin immediately.

Hi,

(Happy 1st of April!?)

ignoring for the moment signal-to-noise ratio issues which will usually
soon limit any reasonable amount of "super"-resolution even with advanced
techniques, the kind of sub-pixel-resolution methods discussed before where
about getting sub-pixel information for edges of SUPER-pixel objects, kind
of "egde sharpening", not of being able to tell what´s inside ONE pixel.

Compare this with the classical resolution limit in microscopy: it´s not
defined as the precision you can achieve in determining the position of a
sub-lambda object (which can pretty easily be better than lambda/NA by
using over-magnification, averaging, fitting etc.), but the ability to tell
TWO very adjacent objects apart, in the classical definition (Rayleigh,
Sparrow) you would like to see at least a small decrease in intensity
between the two "blobs" to tell it´s two.

"True" super-resolution instead is trying to tell, when you see a somewhat
"larger blob", if this is caused by a slightly larger object, or by several
distinct objects and to identify them. This can be tried by deconvolution
techniques, which require a very good model of the transfer function that
caused the degraded image and the amount of super-resolution is strongly
limited by the signal-to-noise ratio, you could say logarithmically: a
pretty large increase in S/N is required to get only a slight increase in
the superresolution factor.

So called "a-prio-information" can help, as is in fact the case in the
above edge detection, where you already know/assume that you are dealing
with a large object, constant over the resolution scale, so the only
information you are seeking is the improved edge position, not any detail
of the edge structure (sharp, soft, composed....).

So, no chance for seeing microbes....

Joachim

Hi there,

somebody should really work on a plugin that allows you to change your
point of view in photographs, so you can look what´s behind other objects.
It must be possible, I saw it in a documentation I think it was called
"blade runner". Any volunteers? If somebody has the algorithm, I would try!

Hi.  There is a tutorial on the IJ website, but I'll tell you all my settings for the project in NetBeans the way I have it set up:
  1. Properties>Sources points to C:\myproject\myBuilds\ImageJPlugins
  2. Source Package Folders points to C:\myproject\mysrc\plugins
  3. Build>Compile Time Libraries points to the ij.jar file and source
  4. Build>Packaging points to c:\ImageJ/plugins/myplugins_.jar
5. The working directory is C:\ImageJ.
  6. The main class for the project is the following:
import ij.ImageJ;
import ij.plugin.PlugIn;
public class RunIJ implements  PlugIn{
       /** Main method in case user wants to double click. Starts ImageJ.
     * @param args String array
     */
    public static void main (String args[])
    {
       
        new ImageJ ();
       
    }
    public void run(String args)
    {new ImageJ ();}
}

Audrey and Wayne,

Thanks for your responses. I have played around with this
problem and I find this seems to be a quirk of my netbeans
installation which I am unable to correct. To get plugins in a
sub-folder of the plugins folder to work, I need to:

1. Create the sub-folder as a new package
2. Create the plugin as described in the netbeans tutorial
3. Move the plugin to the default package under plugins and let
netbeans do "refactoring"
4. Move the plugin source back to the original package and let
netbeans do the refactoring again

Don't know why this works, but it works and I no longer get the
"Plugin not found" message.

Just one comment about the ImageJ website: Under developer
resources, would it not be better to have a link to the netbeans
tutorial? I 'discovered' the tutorial using Google.

Regards,
Divakar

Hi.  Do you have to go through this every time you change the source code and compile or just once for each plugin?

  Audrey and Wayne,

Thanks for your responses. I have played around with this
problem and I find this seems to be a quirk of my netbeans
installation which I am unable to correct. To get plugins in a
sub-folder of the plugins folder to work, I need to:

1. Create the sub-folder as a new package
2. Create the plugin as described in the netbeans tutorial
3. Move the plugin to the default package under plugins and let
netbeans do "refactoring"
4. Move the plugin source back to the original package and let
netbeans do the refactoring again

Don't know why this works, but it works and I no longer get the
"Plugin not found" message.

Just one comment about the ImageJ website: Under developer
resources, would it not be better to have a link to the netbeans
tutorial? I 'discovered' the tutorial using Google.

Regards,
Divakar
