    • Variable Precision Logic 

      Michalski, Ryszard S.; Winston, Patrick H. (1985-08-01)
      Variable precision logic is concerned with problems of reasoning with incomplete information and under time constraints. It offers mechanisms for handling trade-offs between the precision of inferences and the ...
    • The Variational Approach to Shape from Shading 

      Horn, Berthold K.P. (1985-03-01)
      We develop a systematic approach to the discovery of parallel iterative schemes for solving the shape-from-shading problem on a grid. A standard procedure for finding such schemes is outlines, and subsequently used ...
    • Vector-Based Integration of Local and Long-Range Information in Visual Cortex 

      Somers, David C.; Todorov, Emanuel V.; Siapas, Athanassios G.; Sur, Mriganka (1996-01-18)
      Integration of inputs by cortical neurons provides the basis for the complex information processing performed in the cerebral cortex. Here, we propose a new analytic framework for understanding integration within ...
    • Vectorizing Face Images by Interpreting Shape and Texture Computations 

      Beymer, David (1995-09-01)
      The correspondence problem in computer vision is basically a matching task between two or more sets of features. In this paper, we introduce a vectorized image representation, which is a feature-based representation where ...
    • Velocity Space and the Geometry of Planetary Orbits 

      Abelson, Harold; diSessa, Andrea; Rudolph, Lee (1974-12-01)
      We develop a theory of orbits for the inverse-square central force law which differs considerably from the usual deductive approach. In particular, we make no explicit use of calculus. By beginning with qualitative ...
    • Verb Classes and Alternations in Bangla, German, English, and Korean 

      Jones, Douglas A.; Berwick, Robert C.; Cho, Franklin; Khan, Zeeshan; Kohl, Karen T.; e.a. (1996-05-06)
      In this report, we investigate the relationship between the semantic and syntactic properties of verbs. Our work is based on the English Verb Classes and Alternations of (Levin, 1993). We explore how these classes are ...
    • Vertical Image Registration in Stereopsis 

      Nielsen, K.R.K.; Poggio, T. (1983-10-01)
      Most computational theories of stereopsis require a registration stage prior to stereo matching to reduce the matching to a one-dimensional search. Even after registration, it is critical that the stereo matching process ...
    • Very Large Planner-Type Data Bases 

      McDermott, Drew V. (1975-09-01)
      This paper describes the implementation of a typical data-base manaer for an A.I. language like Planner, Conniver, or QA4, and some proposed extensions for applications involving greater quantities of data than usual. ...
    • A View on Dyslexia 

      Geiger, Gad; Lettvin, Jerome Y. (1997-06-01)
      We describe here, briefly, a perceptual non-reading measure which reliably distinguishes between dyslexic persons and ordinary readers. More importantly, we describe a regimen of practice with which dyslexics learn a ...
    • View-Based Models of 3D Object Recognition and Class-Specific Invariances 

      Logothetis, Nikos K.; Vetter, Thomas; Hurlbert, Anya; Poggio, Tomaso (1994-04-01)
      This paper describes the main features of a view-based model of object recognition. The model tries to capture general properties to be expected in a biological architecture for object recognition. The basic module is a ...
    • View-Based Strategies for 3D Object Recognition 

      Sinha, Pawan; Poggio, Tomaso (1995-04-21)
      A persistent issue of debate in the area of 3D object recognition concerns the nature of the experientially acquired object models in the primate visual system. One prominent proposal in this regard has expounded the ...
    • Viewer-Centered Object Recognition in Monkeys 

      Logothetis, N.K.; Pauls, J.; Poggio, T. (1994-04-01)
      How does the brain recognize three-dimensional objects? We trained monkeys to recognize computer rendered objects presented from an arbitrarily chosen training view, and subsequently tested their ability to generalize ...
    • Viewing Control Structures as Patterns of Passing Messages 

      Hewitt, Carl (1976-12-01)
      The purpose of this paper is to discuss some organizational aspects of programs using the actor model of computation. In this paper we present an approach to modelling intelligence in terms of a society of communicating ...
    • Viewpoint-Specific Representations in Three-Dimensional Object Recognition 

      Edelman, Shimon; Bulthoff, Heinrich H. (1990-08-01)
      We report a series of psychophysical experiments that explore different aspects of the problem of object representation and recognition in human vision. Contrary to the paradigmatic view which holds that the representations ...
    • Virtual Visual Hulls: Example-Based 3D Shape Estimation from a Single Silhouette 

      Grauman, Kristen; Shakhnarovich, Gregory; Darrell, Trevor (2004-01-28)
      Recovering a volumetric model of a person, car, or other object of interest from a single snapshot would be useful for many computer graphics applications. 3D model estimation in general is hard, and currently requires ...
    • Visible Decomposition: Real-Time Path Planning in Large Planar Environments 

      Maron, Oded; Lozano-Perez, Tomas (1998-06-01)
      We describe a method called Visible Decomposition for computing collision-free paths in real time through a planar environment with a large number of obstacles. This method divides space into local visibility graphs, ...
    • Vision by Man and Machine 

      Poggio, Tomaso (1984-03-01)
      The development of increasingly sophisticated and powerful computers in the last few decades has frequently stimulated comparisons between them and the human brain. Such comparisons will become more earnest as computers ...
    • A Vision Chip 

      Batali, John (1981-05-01)
      Some well understood and well justified algorithms for early visual processing must be implemented in hardware for later visual processing to be studied. This paper describes the design and hardware implementation of ...
    • The Vision Laboratory: Part One 

      Binford, Thomas O. (1970-07-01)
      Some of the facilities for vision programming are discussed in the format of a user's manual.
    • Vision Memo 

      Minsky, Marvin (1967-02-01)
      This Memo proposes a set of systems programs for vision work. Please comment immediately as we should start on it at once. Values stored outside an array range should have no effect, but set an overflow flag: values read ...
