The Measurement of Visual Motion
(1982-12-01)
The analysis of visual motion divides naturally into two stages: the first is the measurement of motion, for example, the assignment of direction and magnitude of velocity to elements in the image, on the basis of the ...
Qualitative Process Theory
(1983-05-01)
Things move, collide, flow, bend, heat up, cool down, stretch, break and boil. These and other things that happen to cause changes in objects over time are intuitively characterized as processes. To understand common ...
Nonlinear Interactions in a Dendritic Tree: Localization, Timing and Role in Information Processing
(1981-09-01)
In a dendritic tree transient synaptic inputs activating ionic conductances with an equilibrium potential near the resting potential can veto very effectively other excitatory inputs. Analog operations of this type can ...
Open Systems
(1982-12-01)
This paper describes some problems and opportunities associated with conceptual modeling for the kind of "open systems" we foresee must and will be increasingly recognized as a central line of computer system development. ...
Binocular Shading and Visual Surface Reconstruction
(1982-08-01)
Zero-crossing or feature-point based stereo algorithms can, by definition, determine explicit depth information only at particular points on the image. To compute a complete surface description, this sparse depth map ...
LetS: An Expressional Loop Notation
(1983-02-01)
Many loops can be more easily understood and manipulated if they are viewed as being built up out of operations on sequences of values. A notation is introduced which makes this viewpoint explicit. Using it, loops can ...
Policy-Protocol Interaction in Composite Processes
(1982-09-01)
Message policy is defined to be the description of the disposition of messages of a single type, when received by a group of processes. Group policy applies to all the processes of a group, but for a single message ...
Robot Programming
(1982-12-01)
The industrial robot's principal advantage over traditional automation is programmability. Robots can perform arbitrary sequences of pre-stored motions or of motions computed as functions of sensory input. This paper ...
Seeing What Your Programs Are Doing
(1982-02-01)
An important skill in programming is being able to visualize the operation of procedures, both for constructing programs and debugging them. Tinker is a programming environment for Lisp that enables the programmer to ...
A Theoretical Analysis of the Electrical Properties of a X-Cell in the Cat's LGN
(1984-03-01)
Electron microscope studies of relay cells in the lateral geniculate nucleus of the CAT have shown that the retinal input of X-cells is associated with a special synaptic circuitry, termed the spine-triad complex. The ...
