[Insight-users] Problem with MultiResMIRegistration

[Fong Ming Hooi]

Hello,

 

I'm having some trouble with the MultiResMIRegistration program.  I'm using
the input of BrainWebT1toT2b.txt and have been getting this corresponding
output:  

 

Output: 

Parsing input ... 

Fixed image filename:
C:\ITKFiles\ITKAppBin2\MultiResMIRegistration\brainweb165a10f17.mha

Moving image filename:
C:\ITKFiles\ITKAppBin2\MultiResMIRegistration\brainweb1e5a10f17Rot10Tx15.mha

Permute order: [0, 1, 2]

Flip axes: [0, 0, 0]

Number of levels: 5

Fixed image shrink factors: [4, 4, 1]

Moving image shrink factors: [8, 8, 1]

Number of iterations: [2500, 2500, 2500, 2500, 2500]

Learning rates: [0.0001, 1e-05, 5e-06, 1e-06, 5e-07]

Translation scale: 320

Output filename: t1tot2.mhd

Generating output ...

 

 

The output image is unchanged from the moving image.   Does anyone have any
advice as to what I can do to troubleshoot this?  I've built the ITK 1.8
framework using cygwin along with FLTK 1.1.4 and Qt 2.3.1 as well.  Also,
the Hello World example works fine along with the Registration examples.   

 

Thanks,

Fong Ming
