What exactly do you mean by 'decimating'. To me is seems that you are looking for matrix factorization or matrix completion techniques, which are trendy topics in machine learning currently.
By decimating, I mean this:
input array data.shape = (nx, ny, nz) -> data[::ax, ::ay, ::az], ie output array data[::ax, ::ay, ::az].shape = (nx/ax, ny/ay, nz/az).
