  • Ideas About Management of LISP Data Bases 
    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 ...
  • Ill-Posed Problems and Regularization Analysis in Early Vision 
    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 ...
  • Ill-Posed Problems in Early Vision 
    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 ...
  • Image Based Rendering Using Algebraic Techniques 
    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 ...
  • Image-Based View Synthesis 
    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 ...
  • The Image Dissector "Eyes" 
    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 ...
  • Image Intensity Understanding 
    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 ...
  • Imagination and Situated Cognition 
    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 ...
  • Implementation of a Theory for Inferring Surface Shape from Contours 
    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. ...
  • Implementing Universal Computation in an Evolutionary System 
    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 ...
  • The Implicit Constraints of the Primal Sketch 
    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 ...
  • Improving Multiclass Text Classification with the Support Vector Machine 
    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 ...
  • Incorporating MIDAS Routines into PDP-6 LISP 
    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 ...
  • The Incremental Garbage Collection Processes 
    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 ...
  • The Incremental Rigidity Scheme for Recovering Structure from Motion: Position vs. Velocity Based Formulations 
    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 ...
  • Indexing for Visual Recognition from a Large Model Base 
    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 ...
  • The Individual is Nothing, the Class Everything: Psychophysics and Modeling of Recognition in Obect Classes 
    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 ...
  • Infants in Children Stories - Toward a Model of Natural Language Comprehension 
    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 ...
  • Inferring 3D Shapes from 2D Codons 
    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 ...
  • Inferring 3D Structure with a Statistical Image-Based Shape Model 
    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 ...
