Simulation studies on optical illusions based on a position-dependent point spread function

摘要

Basic concepts defined for understanding of optical illusions include a position-dependent PSF (point spread function) and an assumed measure of fixation over the pattern plane. An exact simulation of the famous Hering's illusion has been carried out by employing the position-dependent PSF. Reasonable understanding of the Mueller-Lyer's and Poggendorff's illusions has been achieved in terms of the assumed impressibility measure of fixation. The well-known laterally inhibitory function has been included in the mathematical description of the position-dependent PSF.
