Differential Processing of Objects under Various Viewing Conditions in the Human Lateral Occipital Complex
The invariant properties of human cortical neurons cannot be studied directly by fMRI due to its limited spatial resolution. Here, we circumvented this limitation by using fMR adaptation, namely,Expand

Psychophysical support for a two-dimensional view interpolation theory of object recognition.
Three recently proposed theories of object recognition--viewpoint normalization or alignment of three-dimensional models [Ullman, S. I. (1989) Cognition 32, 193-254], linear combination of two-dimensional views [Poggio, T. & Basri, R. (1990) Recognition by Linear Combinations of Models (Artificial Intelligence Laboratory, Massachusetts Institute of Technology, Cambridge), A.I. Memo No. 1152], and view approximation . Expand

A network that learns to recognize three-dimensional objects
We have developed a scheme, based on the theory of approximation of multivariate functions, that learns from a small set of perspective views a function mapping any viewpoint to a standard view. Expand

Representation and recognition in vision
Representation and Recognition in Vision, Shimon Edelman bases a comprehensive approach to visual representation on the notion of correspondence between proximal and distal similarities in objects. Expand

A sequence of object‐processing stages revealed by fMRI in the human occipital lobe
Functional magnetic resonance imaging was used in combined functional selectivity and retinotopic mapping tests to reveal object‐related visual areas in the human occpital lobe. Subjects were testedExpand

Unsupervised learning of natural languages
We address the problem, fundamental to linguistics, bioinformatics, and certain other disciplines, of using corpora of raw symbolic sequential data to infer underlying rules that govern their production. Expand

Orientation dependence in the recognition of familiar and novel views of three-dimensional objects
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 demonstrated forExpand

Cue-Invariant Activation in Object-Related Areas of the Human Occipital Lobe
The extent to which primary visual cues such as motion or luminance are segregated in different cortical areas is a subject of controversy. To address this issue, we examined cortical activation inExpand

Fast perceptual learning in visual hyperacuity.
In many different spatial discrimination tasks, such as in determining the sign of the offset in avernier stimulus, the human visual system exhibits hyperacuity by evaluating spatial relations with the precision of a fraction of a photoreceptor's diameter. Expand

Long-term learning in vernier acuity: Effects of stimulus orientation, range and of feedback
In hyperacuity, as in many other tasks, performance improves with practice. To better understand the underlying mechanisms, we measured thresholds of 41 inexperienced observers for the discriminationExpand
