Dear Ethan,
Following my E-mail of this morning, you are lucky since I was able to get
hold of my modified version of the StackReg_ plugin I was talking about this
morning.
And here is the description I had put on top of this plugin:
| Translation_Alignment plugin corresponding to a modification of the
| StackReg_ plugin described lower.
| This plugin uses only the "translation transformation" of the
| StackReg_ plugin and applies as well a croping of the outside part
| of the shifted pictures.
| The plugin able to get the translation values of the transformation
| through the macro functions:
| Ext.getShiftValueX1
| Ext.getShiftValueX2
| Ext.getShiftValueY1
| Ext.getShiftValueY2
| Ext.getShiftValueX
| Ext.getShiftValueY
And you will be able to download this plugin under:
http://punias.free.fr/ImageJ/Translation_Alignment.javaHave a nice day,
Philippe

Objet : Re: StackReg x,y translation values
Dear Ethan,
Reading your post, it seems to me that that you have the same application
issues I went through and for which I have spend quite some time.
Indeed, I acquire time lapse pictures of multi positions (on 2-3 channels)
of a sample.
And from all this bunch of data I need then to correct the x-y drift seen
through the time lapse pictures on a channel and apply later on the same
corrections for all the other channels (i.e. I need as well to get out the
x-y translation values of the transformation as you requested).
For doing this job, I first (about 4 years ago) used the StackReg plugin,
until I find some experimental examples with unsolvable issues and moved
then over the JavaSIFT tool.
But I later on got as well some issues with JavaSIFT which made me look as
well for an alternative.
So now I'm using the "Template Matching and Slice Alignment" tool from
Qingzong TSENG:
https://sites.google.com/site/qingzongtseng/template-matching-ij-pluginwhich up to now worked well for really all my acquired data.
Of course for all these tools (i.e. "StackReg", "JavaSIFT" and "Template
Matching and Slice Alignment") I modified the code, for at least be able to
extract the x-y translation values of the transformation.
For example for the "Template Matching and Slice Alignment" tool I'm using
now, I created the following java method:
public static double [] getAlignSlicesDisplacement(ImagePlus _imp,
String _method, int _windowSizeX, int _windowSizeY, int _iniX, int _iniY,
int _sArea, boolean _subPixel, String _itpMethod, int _refSlice, boolean
_showRT)
which able me to get the x-y translation values of the transformation by
even short circuiting all the GUI of the plugin.
But if you want to stay with your first request, which means be able to
extract the x-y translation values of the stackreg transformation, I can
then try to dig into my old codes to see if I can get a hold of the code I
had about 4 years ago (at that time I extracted the x-y translation values
of the transformation through an Ext. feature).
Very unfortunately, as I make now a very ordered archives of all my codes
updates (which I found extremely useful in case of bugs issues) I didn't do
this about 4 years ago. So I can't make you promises whether I can easily
get a hold of the modified StackReg plugin I'm talking about.
At last, in the case you want to look in the direction of UnwarpJ as Michael
recommended you, you will find some commented details of the modification I
made for this plugin as well under:

Objet : StackReg x,y translation values
We are aligning a b/w image stack with StackReg using Rigid Transformation.
Q1: Is there a way to get the x,y, translation values out in a table for the
aligned images translation coordinates relative to the reference image?
The Rigid Registration plug-in has a Euclidean transform output to a log
file, but no switch on StackReg.
StackReg calls TurboReg, and I see a switch in TurboReg (hidden that does
this stackOutput?).
Ethan.
