Paper Abstract

This paper describes a recognition mechanism based on the relationships between interest points and their properties that is applied to the problem of modelling the Poggendorff illusion. The recognition mechanism is shown to perform in the same manner as human vision on the standard illusion and reduced effects are modelled on a variant without parallels. The model shows that the effect can be explained as a perceptual compromise between alignment of the elements in the oblique axis and their displacement from each other in the vertical. In addition an explanation is offered how obtuse angled variants of the Poggendorff figures yield stronger effects than the acute angled variants.
