26 Reconstruction of three-dimensional surfaces from two-dimensional projectionsAbstract: This thesis describes a method for determining the three-dimensional shape of an object from a set of photographs of the objects. For a non-glossy surface, the image brightness is, in theory, a function only of the normal to the surface and of the incident light direction. A reflectivity l...three-dimensional images; image brightness; reflectivity law1981-06
27 A cell-based approach to hierarchical interdomain VLSI designThis dissertation presents a new design environment for VLSI circuits that is based upon a unification of the physical and structural design domains. Unlike conventional design approaches that divide the VLSI design process into disjoint structural and physical design phases, this new environment is...1992-06
28 Digital image deblurring by nonlinear homomorphic fllteringAbstract: This dissertation is concerned with the digital estimation of the frequency response of a two-dimensional linear system through which images have been passed and blurred. Almost no a priori knowledge concerning the system is required, and only one blurred image is necessary for a successfu...Deblurring; nonlinear homomorphic filtering1974-08
29 Real-time measurement of multiple three-dimensional positionsAbstract: This paper describes a priori digital speech analysis. This method takes advantage of the quasi-periodic nature of voice speech sounds to reduce the amount of computation needed to obtain the analysis parameters. The vocal tract is modeled as an all-pole digital filter (predictive coding)...light-emitting diodes; photomultiplier1973-06

Also sho...1968-08
32 3-D Design of Free-Form B-Spline SurfacesThis report describes an experimental system for designing free-form B-spline surfaces using a head-mounted display. In this system, the interaction with the surfaces takes place in three dimensions as the designed object's shape is updated in real-time. The report also examines some of the problems...1974-09
33 A Subdivision Algorithm for Computer Display of Curved SurfacesThis report presents a method for producing computer shaded pictures of curved surfaces. Three-dimensional curved patches are used, as contrasted with conventional methods using polygons. The method subdivides a patch into successively smaller subpatches until a subpatch is as small as a raster- ele...1974-12
34 Feature-based reverse engineering of mechanical parts: revisionReverse engineering of mechanical parts requires extraction of information about an instance of a particular part sufficient to replicate the part using appropriate manufacturing techniques. This is important in a wide variety of situations, since functional CAD models are often unavailable or unusa...1995-11-06
35 A Dynamic Model for Computer-Aided ChoreographyThe application of the digital computer in the field of dance choreography is a relatively unexplored area. The use of the computer in other arts is more widely known.

44 Extraction of Micro-Terrain FeaturesMicro-terrain features are topographic structures relavent to the behavior of a simulation, but with a horizontal extent significantly less than the resolution of the base-level terrain data covering the area in which these structures occur. Thus, these features are not directly extractable from ele...1998-08
45 A Method for Extending FORTRAN V for the Interactive Graphical Solution of Numerical ProblemsInteractive computer graphics offers much in the way of bringing the program user closer to the problem solving algorithm. Techniques may be employed which provide for the execution of the program to be monitored and action taken to help the program find the solution, or to find it more quickly. Log...1968-12
46 Considerations for the Development of a Computer-Aided Electrical Design SystemThe specifications of a computer-aided design system are proposed based on the implementation of a prototype subsystem using UNIVAC 1108 and PDP-8 computers.
