We compare the angular resolution achieved by simple averaging of AO-corrected images (long-exposure), selection and re-centering (shift-and-add or \"lucky\" imaging) and speckle interferometry. The effect of partial AO correction, vibrations, and image post-processing on the attained resolution is shown. Potential usefulness of these techniques is evaluated for reaching the diffraction limit in ","authors_text":"A. Tokovinin, E. Mondaca, M. Martinez, N. van der Bliek, P. Schurter, R. Cantarutti, R.
