A Detailed Look at Scale and Translation Invariance in a Hierarchical Neural Model of Visual Object Recognition
(2002-08-01)The HMAX model has recently been proposed by Riesenhuber & Poggio as a hierarchical model of position- and size-invariant object recognition in visual cortex. It has also turned out to model successfully a number of ... -
Detecting and Tolerating Byzantine Faults in Database Systems
(2008-06-30)This thesis describes the design, implementation, and evaluation of a replication scheme to handle Byzantine faults in transaction processing database systems. The scheme compares answers from queries and updates on multiple ... -
Detecting and tracking multiple interacting objects without class-specific models
(2006-04-25)We propose a framework for detecting and tracking multiple interacting objects from a single, static, uncalibrated camera. The number of objects is variable and unknown, and object-class-specific models are not available. ... -
Detecting Digital Forgeries Using Bispectral Analysis
(1999-12-01)With the rapid increase in low-cost and sophisticated digital technology the need for techniques to authenticate digital material will become more urgent. In this paper we address the problem of authenticating digital ... -
Detecting Faces in Impoverished Images
(2001-11-05)The ability to detect faces in images is of critical ecological significance. It is a pre-requisite for other important face perception tasks such as person identification, gender classification and affect analysis. Here ... -
Detecting Hazardous Intensive Care Patient Episodes Using Real-time Mortality Models
(2009-08-26)The modern intensive care unit (ICU) has become a complex, expensive, data-intensive environment. Caregivers maintain an overall assessment of their patients based on important observations and trends. If an advanced ... -
Determining articulator configuration in voiced stop consonants by matching time-domain patterns in pitch periods
(2005-01-28)In this thesis I will be concerned with linking the observed speechsignal to the configuration of articulators.Due to the potentially rapid motion of the articulators, the speechsignal can be highly non-stationary. The ... -
Determining Attitude of Object from Needle Map Using Extended Gaussian Image
(1983-04-01)An extended Gaussian image (EGI) is constructed by mapping the surface normals of an object onto the Gussian sphere. The attitude of an object is greatly constrained by the global distribution of EGI mass over the ... -
Determining Grasp Points Using Photometric Stereo and the PRISM Binocular Stereo System
(1984-08-01)This paper describes a system which locates and grasps doughnut shaped parts from a pile. The system uses photometric stereo and binocular stereo as vision input tools. Photometric stereo is used to make surface ... -
Determining Optical Flow
(1980-04-01)Optical flow cannot be computed locally, since only one independent measurement is available from the image sequence at a point, while the flow velocity has two components. A second constraint is needed. A method for ... -
Determining Shape and Reflectance Using Multiple Images
(1978-08-01)Distributions of surface orientation and reflectance factor on the surface of an object can be determined from scene radiances observed by a fixed sensor under varying lighting conditions. Such techniques have potential ... -
Determining the Limits of Automated Program Recognition
(MIT Artificial Intelligence Laboratory, 1989-06)Program recognition is a program understanding technique in which stereotypic computational structures are identified in a program. From this identification and the known relationships between the structures, a hierarchical ... -
Determining the Scope of English Quantifiers
(1978-06-01)How can one represent the meaning of English sentences in a formal logical notation such that the translation of English into this logical form is simple and general? This report answers this question for a particular ... -
Deterministic Propositional Dynamic Logic: Finite Models, Complexity, and Completeness
(1981-01)Let p be a formular in deterministic propositional dynamic logic. A decision procedure for the satisfiability of p is given along with a construction of a finite model for every satisifiable p. The decision procedure runs ... -
Developing a Computational Representation for Problem Solving Skills
(1978-10-01)This paper describes the evolution of a problem solving model over several generations of computer coaches. Computer coaching is a type of computer assisted instruction in which the coaching program observes the ... -
Developing a Musical Ear: A New Experiment
(1972-07-01)I would like to report on some ideas we have been developing at M.I.T. for self-paced, independent music study. The aim of our approach is to nurture in students that enigmatic quality called, "musical"-- be it a ... -
The Development of Musical Intelligence I: Strategies for Representing Simple Rhythms
(1975-11-01)This paper is the first in a series of monographs which will describe various aspects of the development of musical intelligence. -
Development of Musical Intelligence II: Children's Representation of Pitch Relations
(1976-12-01)The work reported here is an outgrowth of studies in the development of musical intelligence and learning that have been underway for about four years. Beginning as one of the activities in the LOGO Lab (a part of the ... -
Developmental Cost for Models of Intelligence
(2007-05-15)We can evaluate models of natural intelligence, as well as theirindividual components, by using a model of hardware and developmentcosts, ignoring almost all the details of biology. The basic argumentis that neither the ... -
A Dexterity Measure for the Kinematic Control of Robot Manipulator with Redundany
(1988-02-01)We have derived a new performance measure, product of minors of the Jacobian matrix, that tells how far kinematically redundant manipulators are from singularity. It was demonstrated that previously used performance ...
