Background: Human observers can recognize three-dimensional objects seen in novel
orientations, even when they have previously seen only a relatively small number of different …

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 …

Successful vision systems must overcome differences in two-dimensional input shapes
arising from orientation changes in three-dimensional objects. How the human visual system …

Visually recognizing objects at different orientations and distances has been assumed to
depend either on extracting from the retinal image a viewpoint–invariant, typically three …

To form view-invariant representations of objects, neurons in the inferior temporal cortex
may associate together different views of an object, which tend to occur close together in …

Objects with bilateral symmetry, such as faces, animal shapes, and many man-made
objects, play an important role in everyday vision. Because they occur frequently, it is …

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 …

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 …

We measured the ability to discriminate 3D shapes across changes in viewpoint and
illumination based on rich monocular 3D information and tested whether the addition of …
