The Connection Machine
(1981-09-01)
This paper describes the connection memory, a machine for concurrently manipulating knowledge stored in semantic networks. We need the connection memory because conventional serial computers cannot move through such networks ...
A Computer Implementation of a Theory of Human Stereo Vision
(1980-01-01)
Recently, Marr and Poggio (1979) presented a theory of human stereo vision. An implementation of that theory is presented and consists of five steps: (1) The left and right images are each filtered with masks of four ...
Extra-Retinal Signals Influence Induced Motion: A New Kinetic Illusion
(1980-05-01)
When a moving dot, which is tracked by the eyes and enclosed in a moving framework, suddenly stops while the enclosing framework continues its motion, the dot is seen to describe a curved path. This illusion can be ...
Inferring Shape from Motion Fields
(1980-12-01)
The human visual system has the ability o utilize motion information to infer the shapes of surfaces. More specifically, we are able to derive descriptions of rigidly rotating smooth surfaces entirely from the orthographic ...
Using Parallel Processing for Problem Solving
(1979-12-01)
Parallel processing as a conceptual aid in the design of programs for problem solving applications is developed. A pattern directed invocation language know as Ether is introduced. Ether embodies tow notions in language ...
Shape from Regular Patterns: An Example of Constraint Propagation in Vision
(1980-03-01)
An algorithm is proposed for obtaining local surface orientation from the apparent distortion of surface patterns in an image. A spherical projection is used for imaging. A mapping is defined from points on this image ...
Numerical Shape from Shading and Occluding Contours in a Single View
(1979-11-01)
An iterative method of using occluding boundary information is proposed to compute surface slope from shading. We use a stereographic space rather than the more commonly used gradient space in order to express occluding ...
Constraints on the Visual Interpretation of Surface Contours
(1979-03-01)
This article examines the computational problems underlying the 3-D interpretation of surface contours. A surface contour is the image of a curve across a physical surface, such as the edge of a shadow cast across a ...
Towards a Computational Theory of Semantic Memory
(1980-02-01)
Research in memory has been a frustrating task not least because of the intimate familiarity with what we are trying to understand, and partly also because the human cognitive system has developed as an interactive ...
CADR
(1979-05-01)
The CADR machine, a revised version of the CONS machine, is a general-purpose, 32-bit microprogrammable processor which is the basis of the Lisp-machine system, a new computer system being developed by the Laboratory ...
