The likelihood principle states that the visual system prefers the most likely interpretation of a
stimulus, whereas the simplicity principle states that it prefers the most simple interpretation …

In research on visual shape perception, various models have been designed for the
encoding of visual patterns, in order to predict the human interpretation of such patterns …

It is widely assumed that symmetry is an important visual primitive, probably encoded
without the need for attention. Julesz's (1981) definition of effortless perception, which states …

The research described in this chapter concerns the role of reference frames in perceiving
the shape and orientation of objects. Ultimately, I describe some experiments I have done to …

Detection of runways in aerial images is part of a project to automatically map complex
cultural areas such as a major commercial airport complex. This task is much more difficult …

Representationalism is the position that the phenomenal character of an experience is either
identical with, or supervenes on, the content of that experience. Many representationalists …

The representation of visual information about letters is proposed to be highly systematic,
involving not only abstract information that is invariant across type faces (or fonts), but also a …

There are infinitely many ways in which an object might rigidly move between any two
positions in space. Experiments on real, apparent, and imagined motion indicate, however …

This paper presents a cognitive approach to on-line spatial perception within scenes. A
theoretical framework is developed, based on the idea that experience with a scene can …

Detection of (mirror) symmetry—which is abundantly present in the world—is often assumed
to be an integral part of the perceptual organization process that is applied to every visual …
