[Insight-users] Upsamplig

[Serena Fabbri]

Hi All,
I have a problem with ResampleImageFilter.
I want up-sampling a 2D MR DICOM image.
My image is 176x256 spacing=(1;1)  origin=(1;0) and i want to obtain 392x512 DICOM image.
I am setting spacing=(1*176/392; 1*256/512) and same origin=(1;0).
I utilize IdentityTransform with SetIdentity( ) and LinearInterpolateImageFunction.
The problem is that output image looks enlarged than the original one.

Where do i made a mistake?

Thanks a lot.

Serena
