3-D Design of Free-Form B-Spline Surfaces | This 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 | |

A Dynamic Model for Computer-Aided Choreography | The 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. The report describes an interactive, FORTRAN 5 UNIVAC 1108 computer which relates the angular movements of the joints of the display... | 1970-06 | |

A Parametric Model for Human Faces | This report presents a computer model for the representation of human faces. This three-dimensional, parametric model produces shaded facial images. The face, constructed of polygonal surfaces, is manipulated through the use of parameters which control interpolation, translation, rotation and scalin... | 1974-12 | |

A priori digital speech analysis | Abstract: 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)... | speech analysis; predictor coefficients; pitch period | 1973-03 |

A Subdivision Algorithm for Computer Display of Curved Surfaces | This 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 | |

An Analytical Approach to Computer Systems Scheduling | The report examines some aspects of the problem of allocating resources in a multi-programmed computer system. It first investigates to what extent the users might participate in resource allocation decisions; a system that dynamically determines the prices of services is advocated. A model is studi... | 1970-06 | |

Computer display of curved surfaces | Abstract: This thesis attacks the problem of generating computer synthesized images both more rapidly and more realistically. Increase in speed is achieved by a scan line based algorithm for drawing pictures of parametrically defined curved surfaces. Computation time is reduced by requiring calcula... | computer images; computation time; surfaces | 1978 |

Computer graphics approach for understanding prosthetic heart valve characteristics | Abstract: Fluid dynamics principles and numerical analysis techniques are applied in a study of stress distribution in blood caused by the motion of the occluder within the cage of a prosthetic heart valve model. An interactive computer graphics program is developed for the simulation of the flow pr... | Prosthetic heart valve; Disc occluder; hemolysis; thrombosis | 1972-06 |

Design for a micromodular self-timed system, A | Abstract: Self-timed systems lend themselves readily to interactive design and implementation of concurrency. These systems and their properties are discussed, and the implementation for a micromodular system is described. The use of formal techniques to design asynchronous machines with concurrency... | Switching systems; micromodular representations; self-timed systems; interactive design; concurrency | 1972-03 |

Digital Image Deblurring by Nonlinear Homomorphic Filtering | This report 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 successful estimation. Fo... | 1974-08 | |

Image Recognition Using Generalized Correlation | This paper investigates the use of generalized cross-correlation in pattern matching when the objects may be of one or two dimensions. Generalized correlation can be used to determine the amount of dilatation and rotation between a given template and an object, in addition to determining the relativ... | 1977-08 | |

Noise Suppression Methods for Robust Speech Processing | Robust speech processing in practical operating environments requires effective environmental and processor noise suppression. This report describes the technical findings and accomplishments to develop real time, compressed speech analysis-synthesis algorithms whose performance is invariant under s... | 1979-04 | |

On the rendering of surfaces | Abstract: Despite the relative sophistication of modern surface design systems, many graphical renderings of surfaces are relatively crude. The paper discusses a variety of possible rendering, including various line drawing methods, realistic and functional shading, and ccombinations of line drawing... | surface design systems; graphical renderings; functional shading; curvature shading | 1979 |
