Comparison Of Tissue Classification Using Spin-Echo And Fast Spin-Echo Mri Imaging, Marvin Boonmee

Theses

This study involves the comparison of two image acquisition sequences, the spin-echo (SE) sequence and the fast-spin-echo (FSE) sequence, used in magnetic resonance imaging (MRI). The conventional SE sequence acquires one line of k-space at a time while the FSE sequence can acquire N lines of k-space at a time. FSE scan times are therefore much faster, but the disadvantages include a lower signal-to-noise ratio and reduced accuracy. The purpose of this study is to compare T1, T2, and ρ images calculated from both FSE and SE sequences and to determine if images from the FSE sequence can be corrected, …

Analysis Of The Spectra Of Degraded Documents, Ryan Swift

Theses

The intent of this research was to examine the spectral reflectance of degraded documents to determine whether information is available in regions visible to the human eye. Ultimately we attempt to determine the practicality of manipulating visible (RGB) images to obtain similar information commonly obtained by using infrafred (IR) imaging methods. Charred newspaper was tested as an example of a degraded document. Spectral reflectance of the degraded documents was measured using a fiber optic grating spectrometer. In addition, images were taken of the documents in both the visible (RGB) and infrared (IR) regions of the spectrum. By examining the spectral …

Using Human Observers' Eye Movements In Automatic Image Classifiers, Timothy Grabowski

Theses

This research thesis explored the way in which people look at images in different semantic categories (e.g., handshake versus not-handshake), and directly related those results to computational approaches for automatic image classification. Although many eye tracking experiments have been performed, to our knowledge, this was the first study that specifically compares eye movements across categories, and that links category-specific eye tracking results to automatic image classification techniques. The hypothesis was that the eye movements of human observers for images in different semantic classes differ (e.g., handshakes, others), and that this information can be effectively used in automatic techniques. We presented …

Algorithm For Mtf Estimation By Histogram Modeling Of An Edge, Brian Perry

Theses

The Modulation Transfer Function, or MTF, is a property of an imaging system that describes the effect that the system has on the sharpness of an object. It is an important image quality metric that has applications in almost every major Imaging Science application. The traditional method of determining the MTF, however, relies on aligning an edge perpendicular to the scan line that will be used to take the measurement. This may not always be a convenient orientation for your experiments. It is hypothesized that there is a relationship between the histogram of the scan line (regardless of its position) …

Proof-Of-Concept: Three Dimensional Pipe Surface Reconstruction From 2d Laser Scanned Image, Matthew Altman

Theses

A simulation of three-dimensional models of pipe defect detection systems has been performed. The primary goal is to inspect internal pipe structures for corrosion damage, structural damage, and buildup by driving a video-capture pipe inspection system through the pipe, processing the video, and creating a computer model of the pipe. The software system extracts frames from .avi-format movie files, renders up to thirty frames into a data cube and provides several different methods of visualization. Using commercial-off-the-shelf- technology and components, a simple model for the robotics and optics necessary to scan the interior structure was created. Illumination techniques, extraction algorithms, …

Development Of Non-Contact Scanning Force Microscopy For Imaging In Liquid Environments, Anthony Grant

Theses

The aim of this work was to develop a non-contact mode scanning force microscope (SFM) for application to biological samples within liquid environments. Given that biological samples are particularly soft in their natural state and that a liquid is the most difficult operating environment for non-contact mode scanning force microscopy, the development of an instrument that is optimised to image biological samples in vitro presents significant challenges.

Firstly, the SFM tip to sample interaction has to be minimised either, in the worst case, to prevent the sample from being detached from its support or to maximise spatial resolution by minimising …

Voice Over Ip, Amit Datta, Paul Zam

Theses

The area that this thesis covers is Voice over IP (or IP Telephony as it is sometimes called) over Private networks and not over the Internet. There is a distinction to be made between the two even though the term is loosely applied to both. IP Telephony over Private Networks involve calls made over private WANs using IP telephony protocols while IP Telephony over the Internet involve calls made over the public Internet using IP telephony protocols. Since the network is private, service is reliable because the network owner can control how resources are allocated to various applications, such as …

Developing A Viable Intranet Site, Wendy C, Glidden

Theses

This thesis will focus on establishing consistent guidelines in developing a successful corporate intranet website.

Office intranets are often neglected due to popularity of electronic commerce, and the company's investment in their public website. Standard instructions on how to develop a viable intranet site are not easily found and not likely taught.

With intranet development being a relatively new field, site expectations are very subjective. A site's perceived correctness largely depends on specific goals an organization has established for its site. There are generally high expectations and low budgets for intranets and if usability goals are not kept close at …
