Be careful with the implicitassumption of a model.
• Is this a square?• This is a square• This is not a square
Noise is part of the geometryif no info is given of theunderlying model or the noise

‘Spurious resolution’: artefact of the wrong aperture
What is the best aperture?
Aliasing, partial volume effect
