Improving Quality Consistency And Productivity Of Color Separators Utilizing The Dupont Image Manager, Enrique A. Arce B.

Theses

The magic key in any commercial transaction is to satisfy the customer's requirements. In the color separation market the customer's expectations are consistency in the product, and films that when printed will reproduce a clean visual match to the original copy. The variables that affect the quality, consistency, and productivity for the color separation process, were reviewed. The result of this review was that the operator's scanner set-up for tone reproduction is the most critical variable in the process. An estimate of the total cost in the United States caused by rescans due to inconsistency of the scanner set-up gave …

Felt Garments, Mitsuko Tarui

Theses

This series of garments is my conception of art and fashion. By using different approaches to fiber, I wanted to make each garment unique; giving it its own life and character. By continuously challenging art and fashion, I hope to establish a new category for functional fiber pieces in art. In order to accomplish this goal, "felt" was selected as my main medium. Felt is a unwoven fabric made from wool. It can be shaped into any form, and mixed with different materials. Out of this flexible medium, I wanted to make garments which were like three-dimensional fiber forms rather …

3-D Longwave Infrared Synthetic Scene Simulation, Eric H. Shor

Theses

A technique for thermal infrared (8-14 micrometers) synthetic image generation (SIG) was demonstrated that yields improved radiometric accuracy. This process utilizes the LOWTRAN 6 atmospheric propagation model and computer graphics ray-tracing techniques. A scene is created by placing faceted objects into world coordinates with rotation, translation, and scaling parameters. Each facet is assigned a material index and temperature. This index points to angular emissivity data for that material. LOWTRAN 6 can incorporate a sensor response function when calculating data files for the atmospheric transmission, upwelled and downwelled radiances, and temperature-to-radiance conversions. Ray-traced imagery is generated and discussed. The image is …

Optimal Selection Of Textural And Spectral Features For Scene Segmentation, Wendy Rosenblum

Theses

A study is described in which optimal textural and spectral features are selected for scene segmentation. A set of 46 textural features and 3 spectral features were available for image classification. A method was developed which used a thresholded separability measure to select the best features for scene segmentation. The measure was based on the Mahalanobis distance between class means. The optimal feature selection process was applied to a variety of images and classification results using 4 features ranged from 91% to 97% with independent data sets. The use of the thresholded Mahalanobis-like distance for optimal feature selection was compared …

A Comparison Between The Gca/Gatf Off-Press Proof Comparator And The Gatf Standard Offset Color Control Bar For Identifying When A Cromalin Off-Press Proof Is Prepared To Specification For Web Offset Publication, William F. Breakstone

Theses

Off-press proofing is a method of simulating the way a set of separation negatives or positives will look when printed without having to go to the printing press. In 1965, The Graphic Arts Technical Foundation (GATF) developed a proofing control device for production Lithography. The Standard Offset Color Control Bar was also utilized for off-press proofing. In 1983, The Graphic Communications Association, in cooperation with GATF, introduced The Off-Press Proof Comparator. This control device was designed specifically for this technology and intended to be used by both technical and non-technical personnel with equal and successful results. This thesis is concerned …

The Tug Function: A Method Of Context Sensitive Dot Structuring For Digital Halftones, Steven Hoffenberg

Theses

The process of digitizing images to create halftones inherently reduces sharpness through the averaging of grayness values within cell areas. Within the context of a resolution independent page description language, overcoming this reduced sharpness is conventionally addressed by adjusting the grayness values of cells to create larger or smaller halftone dots where edges are present. Such an approach does not take full advantage of the capabilities of the output device. The objective of this project was to design and implement a method of sharpening digital images by altering the shape and position, rather than the size, of halftone dots. Such …

Modeling Variation In The Refractive Index Of Optical Glasses, David Stephenson

Theses

Experimental measurements that describe the dispersive behavior of production samples of optical glasses are fit with models of minimum complexity for the purpose of in terpolation and extrapolation. Software to perform this procedure on a regular basis is presented, and shown to dis tinguish between models of inappropriate complexity. Two degrees of freedom usually provide a statistically optimum fit to the data contrary to the widespread practice of fit ting a general, six term model to such measurements. Using specially developed analysis tools, it is concluded that annealing does not significantly change the partial dispersion of the sample. Partial dispersion …

On Axial Vibration Of A Web-Idle Roller System, Richard Bomba

Theses

A typical continuous web-processing machine consists of hundreds of idle rollers and web spans. A web span is formed by tensioning a thin film (the web) over at least two idle rollers. Machine drive controls, bearing friction, and air impingement on the web surface represent some of the factors that can influence web tension and web speed. A significant effort is devoted to maintaining uniform web tension and web speed in these machines. The uniformity of these parameters is a requirement to consistently manufacture web products within rigorous quality specifications. In support of this effort to control web tension and …

Expressing Imaging Algorithms Using A C++ Based Image Algebra Programming Environment, Davender Nath Gupta

Theses

Homogeneous Image Algebra is used as the basis for an image processing environment that uses the image, instead of the pixel, as the fundamental unit being manipulated. The object-oriented language C++ is used to implement the environment. Examples of applications are that include filtering, region growing, skeletonization, Fourier Transforms and Hadamard transforms are presented. This thesis concludes that C++ does have several features which are of great benefit in implementing image processing algorithms.
