There is an ITK equivalent, namely itk::ShrinkImageFilter, described here:

    http://www.itk.org/Doxygen/html/classitk_1_1ShrinkImageFilter.html

You may also be interested in the itk::ExtractImageFilter, which lets you
simply collapse dimensions as well as extract regions of interest:

    http://www.itk.org/Doxygen/html/classitk_1_1ExtractImageFilter.html

There is also the related itk::CropImageFilter:

    http://www.itk.org/Doxygen/html/classitk_1_1CropImageFilter.html

Between all these, you should be able to do almost whatever you need.
