  • Sandewall, Erik (1975-05-01)
    The paper advocates the need for systems which support maintenance of LISP-type data bases, and describes an experimental system of this kind, call DABA. In this system, a description of the data base's structure is ...
  • Tomaso, Poggio; Torre, Vincent (1984-04-01)
    One of the best definitions of early vision is that it is inverse optics --- a set of computational problems that both machines and biological organisms have to solve. While in classical optics the problem is to determine ...
  • Bertero, Mario; Poggio, Tomaso; Torre, Vincent (1987-05-01)
    The first processing stage in computational vision, also called early vision, consists in decoding 2D images in terms of properties of 3D surfaces. Early vision includes problems such as the recovery of motion and ...
  • Evgeniou, Theodoros (1996-11-01)
    This paper presents an image-based rendering system using algebraic relations between different views of an object. The system uses pictures of an object taken from known positions. Given three such images it can ...
  • Avidan, Shai; Evgeniou, Theodoros; Shashua, Amnon; Poggio, Tomaso (1997-01-01)
    We present a new method for rendering novel images of flexible 3D objects from a small number of example images in correspondence. The strength of the method is the ability to synthesize images whose viewing position ...
  • Horn, B.K.P. (1969-08-01)
    This is a collection of data on the construction operation and performance of the two image dissector cameras. Some of this data is useful in deciding whether certain shortcomings are significant for a given application ...
  • Horn, Berthold K.P. (1975-08-01)
    Image intensities have been processed traditionally without much regard to how they arise. Typically they are used only to segment an image into regions or to find edge-fragments. Image intensities do carry a great ...
  • Stein, Lynn Andrea (1991-02-01)
    A subsumption-based mobile robot is extended to perform cognitive tasks. Following directions, the robot navigates directly to previously unexplored goals. This robot exploits a novel architecture based on the idea ...
  • Stevens, Kent A. (1982-08-01)
    Human vision is adept at inferring the shape of a surface from the image of curves lying across the surface. The strongest impression of 3-D shape derives from parallel (but not necessarily equally spaced) contours. ...
  • Werfel, Justin (2002-07-01)
    Evolutionary algorithms are a common tool in engineering and in the study of natural evolution. Here we take their use in a new direction by showing how they can be made to implement a universal computer. We consider ...
  • Grimson, W.E.L (1981-10-01)
    Computational theories of structure-from-motion and stereo vision only specify the computation of three-dimensional surface information at points in the image at which the irradiance changes. Yet, the visual perception ...
  • Rennie, Jason D. M.; Rifkin, Ryan (2001-10-16)
    We compare Naive Bayes and Support Vector Machines on the task of multiclass text classification. Using a variety of approaches to combine the underlying binary classifiers, we find that SVMs substantially outperform Naive ...
  • Silver, Roland (1967-03-01)
    Some PDP6 LISP users have felt a need for a way to incorporate MIDAS subroutines into LISP. LISP has been changed to let you do this, using files found on the LISP SYSTEM microtape. You write a routine for LISP in much the ...
  • Baker, Henry G.; Hewitt, Carl (1977-12-01)
    This paper investigates some problems associated with an expression evaluation order that we call "future" order, which is different from call-by-name, call-by-value, and call-by-need. In future order evaluation, an ...
  • Grzywacz, Norberto M.; Hildreth, Ellen C. (1985-10-01)
    Perceptual studies suggest that the visual system uses the "rigidity" assumption to recover three dimensional structures from motion. Ullman (1984) recently proposed a computational scheme, the incremental rigidity ...
  • Breuel, Thomas M. (1990-08-01)
    This paper describes a new approach to the model base indexing stage of visual object recognition. Fast model base indexing of 3D objects is achieved by accessing a database of encoded 2D views of the objects using a ...
  • Riesenhuber, Maximilian; Poggio, Tomaso (2000-05-01)
    Most psychophysical studies of object recognition have focussed on the recognition and representation of individual objects subjects had previously explicitely been trained on. Correspondingly, modeling studies have often ...
  • Meyer, Garry S. (1972-08-01)
    How can we construct a program that will understand stories that children would understand? By understand we mean the ability to answer questions about the story. We are interested here with understanding natural ...
  • Richards, Whitman; Koenderink, Jan J.; Hoffman, D.D. (1985-04-01)
    All plane curves can be described at an abstract level by a sequence of five primitive elemental shapes, called "condons", which capture the sequential relations between the singular points of curvature. The condon ...
  • Grauman, Kristen; Shakhnarovich, Gregory; Darrell, Trevor (2003-04-17)
    We present an image-based approach to infer 3D structure parameters using a probabilistic "shape+structure'' model. The 3D shape of a class of objects may be represented by sets of contours from silhouette views ...
