This dim_vector construction is also wrong. It works for a Matrix as
you saw and as shown in the manual, but for higher dimensional arrays
you should construct it like

  dim_vector dv (resolution[0], resolution[1], 3);

The single-argument form results in a two-dimensional dim_vector
because vectors still have 2 dimensions in Octave.
