Have a look at VSIPL++ ( Vector, Signal, and Image Processing Library ), the spec is here ( ), and an open source
implementation is available if you're interested. VSIPL++ supports 1, 2,
and 3 dimensional containers. Domain objects represent sets of indices
that correspond to a sub-view of the container. An N dimensional Domain
contains a 1D domain for each dimension. If nothing else it may be
helpful to see how others have approached the problem.
