Yes, you can simply write:

saturating_int<int, 1, boost::integer_traits<int>::const_max>::type
ImageBoundary;

Since no int is greater than const_max, the upper bound will never be used for
saturation (and I bet compilers will easily optimise the code eliminating the
comparison with the upper bound).
