Digitized Radio broadcast seeker (DRBS)
… by leveraging pre- developed infrastructure. The Digitized Radio Broadcast Seeker (DRBS) application as an implementation of the application framework provides a platform for web streaming that aggregates web SDRs and helps developers search for broadcast transmissions of interest as well as build …

Enhancing and Reconstructing Digitized Handwriting
… reconstruction, and enhancement of a digitized library of hand-written documents. Imaging systems that perform this digitization often degrade the quality of the original documents. Many techniques exist for reconstructing, restoring, and enhancing digital images; however, many require …

Evolutionary dynamics of digitized organizational routines
This dissertation explores the effects of increased digitization on the evolutionary dynamics of organizational routines. Do routines become more flexible, or more rigid, as the mix of digital technologies and human actors changes? What are the mechanisms that govern the evolution of routines? The …

Deep learning for digitized histology image analysis
… an automated tool to assist pathologists for digitized histology slide analysis. Pre-cervical cancer is generally determined by examining the CIN which is the growth of atypical cells from the basement membrane (bottom) to the top of the epithelium. It has four grades, including: Normal, CIN1, …

Left ventricular boundary detection in digitized cardiac images
<p>Edge detecting techniques relative to application in a portion of Eastern Washington University's Heart Modeling System (HMS) are discussed. Filters, sharpeners, and transforms are discussed in more depth. Twelve operators, several with more than one mask, are tested to arrive at the optimal …

Methods for recognizing patterns in digitized line drawings
… and storage of line and region data from digitized engineering line drawings, first proposed by Watson et.al.[3] and further developed by Bixler et.al.[4], is completed. As a means for the automatic analysis of picture content, a model based recognizer for line patterns is developed. The …

The digitized infant : a field study of entangled emotions and affordances.
The digitization of one's personal data is of growing interest in the information systems discipline. Parents digitizing their infant's personal data in the form of infant monitoring is of particular interest. This study examines emotions and affordances within the context of remote infant …

Segmentation and scale detection algorithms for automated analysis of digitized historical maps
… from various sources of error in the digitized historical map images, including clutter such as text impinging on the region of interest, low contrast between light and dark dashes of the neatline, as well as other sources. The application of our work has been to compare shape …

Using digitized herbarium specimens to predict potential distributions of Tennessee's historical angiosperm species
… task more feasible. Here, SDMs are trained using digitized herbarium specimens to identify suitable habitat and therefore, the potential distribution of 16 historical plant species in Tennessee. The ultimate goal of this work is to provide conservation managers with an effective tool for guiding …

Automated evaluation of radiodensities in a digitized mammogram database using local contrast estimation
… identifying and quantifying radiodense tissue in digitized mammograms have fallen short of the ideal. Many algorithms require significant heuristic parameters to be evaluated and set for predicting radiodensity. Many others have not demonstrated the efficacy of their techniques with a sufficient …

An automatic system for converting digitized line drawings into highly compressed mathematical primitives
The design of an efficient, low-cost system for automatically converting a hardcopy technical drawing into a highly compressed electronic representation is the motivation for this work. An improved method for extracting line and region information from a typical engineering drawing is presented. An …

Automated segmentation of radiodense tissue in digitized mammograms using a constrained Neyman-Pearson classifier
… the percentage of radiodense tissue in a digitized mammogram. The technique involves determining a dynamic threshold for segmenting radiodense indications in mammograms. Both the mammographic image and the threshold are modeled as Gaussian random variables and a constrained Neyman-Pearson …

Spatially varying threshold models for the automated segmentation of radiodense tissue in digitized mammograms
… the amount of radiodense tissue found in a digitized mammogram. The algorithm employs a radial basis function neural network in order to segment the breast tissue region from the remainder of the X-ray. A spatially varying Neyman-Pearson threshold is used to calculate the percentage of …

Developing an operational procedure to produce digitized route maps using GPS vehicle location data
… develop an operational procedure to obtain the digitized route map of any desired interval or link length and to examine the accuracy of the digitized map. The operational procedure involved data collection, data processing, algorithm development and coding to produce the digitized route maps. …

Detection of breast cancer microcalcifications in digitized mammograms. Developing segmentation and classification techniques for the processing of MIAS database mammograms based on the Wavelet Decomposition Transform and Support Vector Machines
Mammography is used to aid early detection and diagnosis systems. It takes an x-ray image of the breast and can provide a second opinion for radiologists. The earlier detection is made, the better treatment works. Digital mammograms are dealt with by Computer Aided Diagnosis (CAD) systems that can …
