Hi all:
I'm sorry for this silly question, but I am new to ITK (and also the
rest of the basic things, as C++, VTK, Qt, which are the tools I'm
trying to bring together). To me I see a huge field for just an
apprentice.
At this time I'm doing rigid registration in the following manner:
FixedImage MovingImage

\/ \/ =20
itkCannyEdgeDetectorFilteri =20
itkCannyEdgeDetectorFilter
|| =20
\/ =20
itkDanielssonDistanceMapImageFilter
||
||
||
\/
itkTranslationTransform
||
\/
itkRegularStepGradientDescentOptimizer
||
\/
itkMeanSquaresPointSetToImageMetric
||
\/
itkLinearInterpolateImageFunction
||
\/
itkPointsetToImageRegistrationMethod
The trouble I get is that the images, far to converge, go the other way
round. The results of the registration algorithm are:
Result =3DTranslation X =3D -90.4793
Translation Y =3D 103.5
Iterations =3D 99
Metric value =3D 1.04037e+09
Could anyone give a hint on how I can solved this to cross over such a
task?
Thanks in advance,
