<p class=MsoNormal><font size=3 color=black face="Times New Roman"><span
style='font-size:12.0pt'>Hi Fong,<br>
<br>
Your problem is related to the minor descripency in VNL behaviour in Cygwin.
I've given a temporary fix below that should make your code work, before we
commit those changes. Thanks for pointing out.<br>
<br>
Just add the line <br>
ReinitializeSeed();<br>
in the constructor MutualInformationImageToImageMetric < , >
::MutualInformationImageToImageMetric()<br>
<br>
Now your code should work fine with Cygwin. If you want to know why, read the
explanation below:<br>
<br>
Basically the family of pseudo-random generators, ie drand48(), lrand48(), or
mrand48(), seem to behave differently under different operating systems.
Strictly speaking, before any calls to these functions are made, we need to go
through initialization entry points, srand48(), seed48() and lcong48()
respectively to initialize the seed. Now, on most compilers relax this
behaviour and supply a default seed. Cygwin's gcc does not. So all calls to
vnl_sample_normal, vnl_sample_uniform etc failed in Cygwin since they are often
called without seeding in ITK. <br>
<br>
Your MultiresMIRegistration example uses the
MutualInformationImageToImageMetric, which uses a
ImageRandomConstIteratorWithIndex to randomly pick evaluation points. VNL is
used to generate these random numbers. <br>
<br>
A more exact solution would be to replace ReinitializeSeed() with
ReinitializeSeed(vcl_time(0)). This does a quasi-random initialization. You
will now need to include the file "vcl_ctime.h"<br>
<br>
Thanks<br>
Hope this helps<br>
