Exploiting Sequential Phonetic Constraints in Recognizing Spoken Words
(1985-10-01)
Machine recognition of spoken language requires developing more robust recognition algorithms. The current paper extends the work of Shipman and Zue by investigating the power of partial phonetic descriptions. First ...
A Robust Layered Control System for a Mobile Robot
(1985-09-01)
We describe a new architecture for controlling mobile robots. Layers of control system are built to let the robot operate at increasing levels of competence. Layers are made up of asynchronous modules which communicate ...
The Synthesis of Force-Closure Grasps
(1985-09-01)
This paper addresses the problem of synthesizing planar grasps that have force closure. A grasp on an object is a force closure grasp if and only if we can exert, through the set of contacts, arbitrary force and moment on ...
Direct Passive Navigation: Analytical Solution for Planes
(1985-08-01)
In this paper, we derive a closed form solution for recovering the motion of an observer relative to a planar surface directly from image brightness derivatives. We do not compute the optical flow as an intermediate ...
Edge Detection
(1985-09-01)
The goal of vision is to recover physical properties of objects in a scene, such as the location of object boundaries and the structure, color, and texture of object surfaces, from the two-dimensional image that is ...
Local Rotational Symmetries
(1985-08-01)
This thesis describes a new representation for two-dimensional round regions called Local Rotational Symmetries. Local Rotational Symmetries are intended as a companion to Brady's Smoothed Local Symmetry Representation ...
A Mobile Robot Project
(MIT Artificial Intelligence Laboratory, 1985-02)
We are building a mobile robot which will roam around the AI lab observing and later perhaps doing. Our approach to building the robot and its controlling software differs from that used in many other projects in a number ...
The Incremental Rigidity Scheme for Recovering Structure from Motion: Position vs. Velocity Based Formulations
(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 ...
Prism Trees: An Efficient Representation for Manipulating and Displaying Polyhedra with Many Faces
(1985-04-01)
Computing surface and/or object intersections is a cornerstone of many algorithms in Geometric Modeling and Computer Graphics, for example Set Operations between solids, or surface Ray Casting display. We present an ...
The Computational Approach to Vision and Motor Control
(1985-08-01)
Over the past decade it has become increasingly clear that to understand the brain, we must study not only its biochemical and biophysical mechanisms and its outward perceptual and physical behavior. We also must study ...
