Use marching cubes, get the triangles, sum their area. It will be an
approximation, but a rather good one.

You can use the ImageJ_3D_Viewer.jar to get the skin. Then either query
it with a java plugin to get the triangles from the Contents, or export
to DXF or Wavefront (the latter is easier) and compute it with a small
python script or something.

I will add the surface triangles sum to the ImageJ_3D_Viewer.jar soon.
