Noisy surfaces, fine details, old graffiti

Hi all I have been working on this point cloud for some time, with little positive outcome. Before I give up, I wondered whether someone more skilled, from the community, might have any advice?!

Even using the classifiers on the CANUPO website, in a different context (a park scene) I managed to remove trees and bushes, lamposts etc. However, I'm now moving to a more difficult context.
