Perceptually optimal sampling of images

F.J.J. Blommaert

Research output: Contribution to journalArticleAcademicpeer-review


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.
