Recovery of 3-D shape from binocular disparity and structure from motion
TL;DR: The findings indicate that the processing of depth information from SFM and binocular disparity is not strictly modular, and thus theories of combining visual information that assume strong modularity-or-independence cannot accurately characterize all instances of depth perception from multiple sources.

Abstract: Four experiments were conducted to examine the integration of depth information from binocular stereopsis and structure from motion (SFM), using stereograms simulating transparent cylindrical objects. We found that the judged depth increased when either rotational or translational motion was added to a display, but the increase was greater for rotating (SFM) displays. Judged depth decreased as texture element density increased for static and translating stereo displays, but it stayed relatively constant for rotating displays. This result indicates that SFM may facilitate stereo processing by helping to resolve the stereo correspondence problem. Overall, the results from these experiments provide evidence for a cooperative relationship between SFM and binocular disparity in the recovery of 3-D relationships from 2-D images. These findings indicate that the processing of depth information from SFM and binocular disparity is not strictly modular, and thus theories of combining visual information that assume strong modularity or independence cannot accurately characterize all instances of depth perception from multiple sources.

Measurement and Modeling of Depth Cue Combination: in Defense of Weak Fusion
TL;DR: This paper argues that the MWF model is consistent with previous experimental results and is a parsimonious summary of these results, and describes experimental methods, analogous to perturbation analysis, that permit us to analyze depth cue combination in novel ways.

Psychoanatomical substrates of Bálint's syndrome.
Matthew Rizzo,Shaun P. Vecera +1 more
TL;DR: Studies of Bálint's syndrome have provided unique evidence on neural substrates for attention, perception, and visuomotor control and future studies should address possible underlying psychoanatomical mechanisms at “bottom up” and “top down” levels.

The visual perception of 3-D shape from multiple cues: are observers capable of perceiving metric structure?
James T. Todd,J. Farley Norman +1 more
TL;DR: Findings provide strong evidence that human observers do not have accurate perceptions of 3-D metric structure.
Systematic distortion of perceived three-dimensional structure from motion and binocular stereopsis.
TL;DR: The results reveal that observers' judgments of 3-D shape from binocular stereopsis and motion contained systematic distortions: Perceived 3- D shape from motion was not invariant over orientation change and perceived3-D structure from stereo, and motion and stereo in combination was not covariant over changes in viewing distance.

TL;DR: An algorithm is presented for enhancing stereo depth cues for moving computer generated 3D images and has the effect of doubling the stereo depth in flat scenes and limiting the stereodepth for deep scenes.

The modularity of mind
Robert Cummins,Jerry A. Fodor +1 more
Abstract: This monograph synthesizes current information from the various fields of cognitive science in support of a new theory of mind. Most psychologists study horizontal processes like memory. Fodor postulates a vertical and modular psychological organization underlying biologically coherent behaviours. This view of mental architecture is consistent with the historical tradition of faculty psychology while integrating a computational approach to mental processes. One of the most notable aspects of Fodor’s work is that it articulates features not only of speculative cognitive architecture but also of current research in artificial intelligence. – Part I. Four accounts of mental structure; – Part II. A functional taxonomy of cognitive mechanisms; – Part III. Input systems as modules; – Part IV. Central systems; – Part V. Caveats and conclusions. M.-M.

TL;DR: It is shown that this algorithm successfully extracts information from random-dot stereograms, and its implications for the psychophysics and neurophysiology of the visual system are briefly discussed.

Detection of binocular disparities
TL;DR: This work identifies one general characteristic of objects in the three dimensional world and uses it to formulate a simple noniterative, parallel and local algorithm that successfully detects disparities generated by opaque as well as transparent surfaces.
