An Airborne Thermal Remote Sensing Calibration Technique, I. D. Macleod
An Airborne Thermal Remote Sensing Calibration Technique, I. D. Macleod
Theses
A calibration technique for airborne thermal remote sensing systems without the requirement for ground truth or multiple altitude measure ments is developed and evaluated. This technique is based on vertical and offset look angles and in effect corrects for image degradation due to atmospheric effects . The results were evaluated by comparison to a multiple altitude regression technique using previously generated imagery, and by statistical methods, including an error analysis. Assuming that the multiple altitude regression technique was exact, the error on apparent temperature produced by this angular technique was 0.32C.

The Application Of The Conjugate Gradient Method To The Solution Of Transient Electromagnetic Scattering From Thin Wires, Sadasiva M. Rao, Tapan K. Sarkar, Sohail A. Dianat
The Application Of The Conjugate Gradient Method To The Solution Of Transient Electromagnetic Scattering From Thin Wires, Sadasiva M. Rao, Tapan K. Sarkar, Sohail A. Dianat
Articles
Previous approaches to the problem of computing scattering by conducting bodies have utilized the well-known marching-on-in-time solution procedures. However, these procedures are very dependent on discretization techniques and sometimes lead to instabilities as the time progresses. Moreover, the accuracy of the solution cannot be verified easily, and usually there is no error estimation. In this paper we describe the conjugate gradient method for solving transient problems. For this method, the time and space discretizations are independent of one another. The method has the advantage of a direct method as the solution is obtained in a finite number of steps and …

Information Theoretic Metrics For The Assessment Of Digital Image-Tone Restored Images, Paul W. Melnychuck
Information Theoretic Metrics For The Assessment Of Digital Image-Tone Restored Images, Paul W. Melnychuck
Theses
Digital image-tone restoration is examined in terms of information theoretic-based measurements. The metrics illustrate the relative degree of restorability of a 6-stop underexposure range on Kodak Tri-X pan film. An image chain model is developed to account for the discrete nature of sampled images used in digital image processing. The model includes the major system components (from object to viewed image) from which the system signal-tonoise ratio is calculated. Quantization noise and clipping are treated as signal-dependent, additive noise sources, and are shown to play a major role in degrading restored images. Although the eye characteristics are not included in …
Optimization Of Vehicle Suspensions Subjected To Random Excitation, Rifaquat Ali Cheema
Optimization Of Vehicle Suspensions Subjected To Random Excitation, Rifaquat Ali Cheema
Theses
This study provides basic information on the analysis and optimization of vehicle suspension systems with a damped absorber attached to the sprung mass and the un sprung mass. This study is also concerned with comparing these systems with a optimized conventional system. A two degree of freedom linear model subjected to guideway irregularity, described as a hyperbolic displacement spectral density, random excitation is chosen for studying the system. Dimensionless space and design parameters are selected to allow for adequate generality. The objective function incorporates the tire-terrain normal force, as an indication of the vehicle controllability, constrained by the sprung mass …
Application Of Least Square Cubic Splines To The Analysis Of Edges, Roland Walter Porth
Application Of Least Square Cubic Splines To The Analysis Of Edges, Roland Walter Porth
Theses
A technique using least square cubic splines was developed to obtain an estimate of the MTF from edge response measurements. By making specific assumptions concerning the general nature of edges to be analyzed, an optimized procedure was developed to fit noise free cummulative gaussian edges. The procedure was evaluated using simulated data from various spread function shapes and levels of additive noise. The spline technique produced MTF estimates which had less bias and lower variance than the commonly used derivative - transform technique. Due to the various constraints which can be imposed on the spline, least square cubic splines actually …
A Signal-To-Noise Ratio Analysis Of An Autoradiographic Image Enhancement Process, Donald R. Williams
A Signal-To-Noise Ratio Analysis Of An Autoradiographic Image Enhancement Process, Donald R. Williams
Theses
A signal-to-noise ratio(SNR) analysis of a S-35 thiourea autoradiographic image enhancement process incorporating subproportional bleaches is performed, with emphasis on diagnostic medical Imagery. Quantifying SNR through a spatial frequency definition of DQE and NEQ, these metrics were compared between donor and receiver-composite stages. While improvements in radiometric speed and gamma were noted in the receiver-composite, these gains were more than offset in a SNR sense by correspondingly lower MTF and higher Wiener spectrum values. As a result the donor's DQF_max of .30 exceeded that of the receiver-composite's DQE_max by 50%. Similarly, ImCXA the donor's NEQ_max exceeded that of the receiver …

Diversion Of Force, Linda J. Moughemer
Theses
I intend to complete a body of work using the concept of diversion of force as a departure point. A paper which will include the organic and inorganic scientific references which have affected my thinking and visual imagery will accompany and support the studio work. Other sources which have aided my exploration of the subject will also appear in the written presentation.

A Quantitative Image Evaluation Study Of A Concurrent Photon Amplification Treated Emulsion, Konrad E. Kern
A Quantitative Image Evaluation Study Of A Concurrent Photon Amplification Treated Emulsion, Konrad E. Kern
Theses
A study was performed to evaluate the effect of concurrent photon amplification (CPA) on Kodak Tri-X Pan emulsion in regard to image quality. The study evaluated detective quantum efficiency (DQE), modulation transfer function (MTF), and information content (IC) as a function of exposure in a comparison between normal exposure and CPA. The results showed CPA to enhance image quality relative to normal exposure at very low exposure levels. As the exposure was increased, normally exposed images became comparable and then exceeded CPA exposures in image quality. The exposure level at which normal exposure became preferential was distinct with each image …
