In this report we discuss a variety of psychophysical experiments that explore different
aspects of the problem of object recognition and representation in human vision. In all …

Does the human brain represent objects for recognition by storing a series of two-
dimensional snapshots, or are the object models, in some sense, three-dimensional analogs …

A key question concerning the perception of 3D objects is the spatial reference frame used
by the brain to represent them. The celerity of the recognition process could be explained by …

Theories of visual object recognition must solve the problem of recognizing 3D objects given
that perceivers only receive 2D patterns of light on their retinae. Recent findings from human …

Successful object recognition is essential for finding food, identifying kin, and avoiding
danger, as well as many other adaptive behaviors. To accomplish this feat, the visual system …

Background: How do we recognize visually perceived three-dimensional objects,
particularly when they are seen from novel view-points? Recent psychophysical studies …

We report four experiments that investigated the representation of novel three-dimensional
(3D) objects by the human visual system. In the first experiment, canonical views were …

Visual object recognition is complicated by the fact that the same 3D object can give rise to a
large variety of projected images that depend on the viewing conditions, such as viewing …

This report describes the main features of a view-based model of object recognition. The
model does not attempt to account for specific cortical structures; it tries to capture general …

Despite the fact that we necessarily view objects from one particular position, we generally
achieve representations of them that transcend that special viewpoint. Shape constancy can …
