Boll, Steven F. | Selected methods for improving synthesis speech quality using linear predictive coding: system description, coefficient smoothing and streak | This report develops two generalizations of the standard Linear Predictive Coding (LPC) implementation of a narrow band speech compression system. The purpose of each method is to improve the speech quality that is available from a standard LPC system. | Linear Predictive Coding; LPC; Speech compression system; Pitch excited system | 1974 |

Vickers, Donald Lee | Sorcerer's apprentice: head-mounted display and wand | Sorcerer's Apprentice is an interactive computer graphics system utilizing a head-mounted display and at three-dimensional wand. The system allows three-dimensional interaction with line drawings which are displayed in real time, that is about 20 frames per second. The display, worn like a pair of e... | Sorcerer's apprentice; Head-mounted display; Three-dimensional wand | 1974 |

Cole, Edwin Randolph | The removal of unknown image blurs by homomorphic filtering | This report describes a homomorphic method for the estimation and removal of unknown image blurs, which are presumed to have been caused by a linear stationary system. Previous methods have required a more or less perfect a priori knowledge of the identity of the blur. the method described here requ... | Homomorphic filtering; Removal; Image blurs; Blurred image | 1974 |

Baxter, Brent S. | Image processing in the human visual system | This work extends the multiplicative visual model to include image texture as suggested by experiments [Campbell, Weisel] linking a low resolution Fourier analysis with neurons in certain parts of the visual cortex. The new model takes image texture into account in the sense that weak texture is acc... | Human visual system; Image texture | 1975 |

Parke, Frederic Ira | 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... | Parametric model; Human face | 1975 |

Rom, Raphael Jona | Image transmission and coding based on human vision | In recent years more and more attention was paid to digital image processing especially as the result of the development of highly efficient algorithms and also because of technologically better facilities. Concurrently attempts were made to find a mathematical model for human vision to achieve a be... | Image transmission; Image coding; Human vision | 1975 |

Ingebretsen, Robert Bergstrom | Log spectral estimation for stationary and nonstationary processes | This research is concerned with two log spectral estimators in the context of both stationary and nonstationary signals. They differ because in one smoothing is realized before the logarithmic transformation, while the other is smoothed in the logarithimc domain. It is shown that for stationary sign... | Log spectral estimation; Nonstationary processes; Log spectral estimators | 1975 |

Crow, Franklin C. | The aliasing problem in computer-synthesized shaded images | This paper describes work toward improving the quality of computer-synthesized shaded images. Current (practical) hidden-surface algorithms produce an image whose precision is strictly limited by the number of picture elements.
