Adaptation Of Lr Parsing To Production System Interpretation, Louis Paul Slothouber Jan 1989

Adaptation Of Lr Parsing To Production System Interpretation, Louis Paul Slothouber

Dissertations, Theses, and Masters Projects

This thesis presents such a new production system architecture, called a palimpsest parser, that adapts LR parsing technology to the process of controlled production system interpretation. Two unique characteristics of this architecture facilitate the construction and execution of large production systems: the rate at which productions fire is independent of production system size, and the modularity inherent in production systems is preserved and enhanced. In addition, individual productions may be evaluated in either a forward or backward direction, production systems can be integrated with other production systems and procedural programs, and production system modules can be compiled into libraries and …

Small-Kernel Image Restoration, Stephen Edward Reichenbach Jan 1989

Small-Kernel Image Restoration, Stephen Edward Reichenbach

Dissertations, Theses, and Masters Projects

The goal of image restoration is to remove degradations that are introduced during image acquisition and display. Although image restoration is a difficult task that requires considerable computation, in many applications the processing must be performed significantly faster than is possible with traditional algorithms implemented on conventional serial architectures. as demonstrated in this dissertation, digital image restoration can be efficiently implemented by convolving an image with a small kernel. Small-kernel convolution is a local operation that requires relatively little processing and can be easily implemented in parallel. A small-kernel technique must compromise effectiveness for efficiency, but if the kernel values …
