[Insight-users] re:resampling a binary image...

Hi, 

You can do it as follow,
 
this->resampler->SetInput(this->inImage);

 this->transform->SetIdentity();

 this->resampler->SetTransform(this->transform);

//Note that the interpolator is NearestNeighborInterpolateImageFunction
 this->resampler->SetInterpolator(this->interpolator);

 this->resampler->SetOutputOrigin(this->inImage->GetOrigin());

 this->resampler->SetDefaultPixelValue( 0 );

 this->resampler->SetOutputSpacing( spacing );//resampled spacing 1.25x1.0x1.0

 this->resampler->SetSize( size );//resampled size 160x256x256

//if the resampled size is change you need to use this->UpdateLargestPossibleRegion()
 this->Update();

 

Regards,

Hello,
   
  I have a 3D binary image of size 80x128x128 and spacing 0.5x0.5x0.5mm. I need to resample the image to get size 160x256x256 with spacing 1.25x1.0x1.0. Does somebody know how to go about it? Appreciate it.
