[Insight-users] Fwd: 3D registration and Analyze (o .mha) images

[S.]

Thank you, Luis, for your interest
I want to reply to your questions.

The images that I used and outputs are in
http://www.fisica.unile.it/~favetta/allow_listing/
Command is    ~/InsightToolkit-3.4.0/Examples/Registration>
./ImageRegistration1 fixed.hdr  moving.hdr imageregistration1.hdr
differencebefore1.hdr differenceafter1.hdr
These are the results:
0 = 2.87669e+06 : [-0.597635, 0.241743, -3.94771]
1 = 2.69077e+06 : [1.24402, -0.515439, -4.13477]
2 = 2.74952e+06 : [0.87942, -2.43264, -3.69727]
3 = 2.73323e+06 : [1.98511, -3.76758, -4.69496]
4 = 2.80148e+06 : [3.71661, -3.70127, -5.69372]
5 = 2.84545e+06 : [2.84814, -3.74008, -6.18794]
6 = 2.71808e+06 : [2.11758, -3.75237, -6.87067]
7 = 2.7094e+06 : [2.59063, -3.644, -6.75032]
8 = 2.73666e+06 : [2.34906, -3.69144, -6.79389]
9 = 2.74714e+06 : [2.12615, -3.78324, -6.86007]
10 = 2.70671e+06 : [2.23996, -3.73913, -6.83315]
11 = 2.72413e+06 : [2.35017, -3.69136, -6.79853]
12 = 2.7467e+06 : [2.29239, -3.71337, -6.80767]
13 = 2.73484e+06 : [2.32201, -3.70391, -6.80455]
14 = 2.74081e+06 : [2.30653, -3.7035, -6.80242]
Result =
 Translation X = 2.30653
 Translation Y = -3.7035
 Iterations    = 16
 Metric value  = 2.73728e+06

> 1) What is the pixel type of your images?
16-bit int

> 2) What is the pixel spacing of your fixed image and moving image
1.2 mm (but I am not sure of this value) on X, 0.9375 on Y and Z

>3) What is their origin coordinates in millimeters
0 0 0

>4) what is the number of pixels along each dimension
166 256 256

>5) What specific * * image registration example are you trying.
I use ImageRegistration1, but I have similar problems with other filters.
Thank you for your time and consideration,
Sandro
