[Insight-users] Re: a question about Resample

[Luis Ibanez]

Hi Yongming,

One easy way to go is to use the ResampleImageFilter
followed by the ExtractImageFilter.

In the ResampleImageFilter you ask for computing as
output a 3D image with thickness of 1 slice. Then in
the ExtractImageFilter you reduce this 1-slice 3D image
to a 2D image. This last filter allows you to reduce the
dimensionality of the image.

You will find examples on the use of ExtractImageFilter
in:

   Regards,



     Luis
