Wavelet-based 2D Multifractal Spectrum with Applications in Analysis of Digital Mammography Images
(Georgia Institute of Technology, 2007-07-26)
Breast cancer is the second leading cause of death in women in the United States and at present, mammography is the only proven method that can detect minimal breast cancer. On the other hand, many medical images demonstrate ...
The Effectiveness of Sealants in Managing Carious Lesions
(Georgia Institute of Technology, 2007)
A barrier to providing sealants is concern about inadvertently sealing over caries. The objective of this meta-analysis was to examine whether sealants are effective in preventing caries progression. Methods: Our search ...
Wavelet Image Interpolation (WII): A Wavelet-Based Approach to Enhancement of Digital Mammography Images
(Georgia Institute of Technology, 2007)
Cancer detection using mammography focuses on characteristics of tiny microcalcifications, including the number, size, and spatial arrangement of microcalcification clusters as well as morphological features of individual ...
Testing Equality of Stationary Autocovariances
(Georgia Institute of Technology, 2007-08-09)
This paper studies tests for assessing whether two stationary and independent time series have the same dynamics, specifically, whether the autocovariances of both series coincide at all lags. Several frequency domain ...
On Bayesian estimation of multinomial probabilities under incomplete experimental information
(Georgia Institute of Technology, 2007-05-28)
In this note, we discuss Bayesian estimation of multinomial probabilities associated with a finite alphabet A, under incomplete experimental information. Two types of prior information are considered: (i) number of letters ...
Bayesian Spherical Wavelet Shrinkage: Applications to Shape Analysis
(Georgia Institute of Technology, 2007)
Multiscale analysis has become a very useful tool in image processing and computer vision. Our work is motivated by the need to efficiently represent 3D shapes that exhibit a spherical topology. This note presents a wavelet ...
Self-similarity in NMR spectra: an application in assessing the level of cysteine
(Georgia Institute of Technology, 2007-01-15)
High resolution of NMR spectroscopic data of biosamples are a rich source of information on the metabolic response to physiological variation or pathological events. There are many advantages of NMR techniques such as the ...
