Abstract
The sampling of images may evoke undesirable perceptual phenomena, such
as spatial structure, field flicker, line flicker and Moiré patterns. The visibility
of these artefacts depends both on the nature of the sampling strategy and on
the characteristics of vision. The present paper shows how sampling strategies
can be optimized from a perceptual point of view. The described computational
theory is based on lattice theory and uses the concept of a 'visibility window'
in the frequency domain.
