<DIV><SPAN class=234523806-09092009><FONT face=Arial size=2>I am a newbie in ITK
and I tried to use the ImageRegistration1.cxx with 2 (very) simple images. The
fixed image was a 168x168 null image (pixel spacing = 1.0 and element size
= 1.0) where I drew a centered filled square (pixel value = 35). The moving
image was the same image with a simple translation of the square (dx = 10, dy =
5 pixels). When using ImageRegistration1 (MaximumStepLenght = 4.0,
MinimumStepLenght=0.01, MaximizeOff, NumberOfIterations=200, MinimizeOn) with
these data, the algorithm stops after only 17 iterations and gives
translation parameters equal to dx=10.0000014214 dy=4.999978 and a final final
non-equal to 0 (around 3e-9). Why ImageRegistration1 can not find the real
solution on a so simple test data set ?</FONT></SPAN></DIV>
