Super Resolution Of Fingerprints, Kaustubh R. Deshpande

Graduate Theses, Dissertations, and Problem Reports (ETD)

The goal of any biometric recognition algorithm has been to target 100% recognition rate. Even a failure of 0.1% of the cases may be disastrous to the overall performance of the algorithm given the nature of the application. The performance of the recognition module is dependent directly on the quality of the images fed to this algorithm. It is no wonder thus that enhancing these images before they are fed into the recognition algorithm has gained importance in the recent years.;In this work, we develop a super-resolution method with a specific goal to improve the resolution of biometric images.

Uncertainty Analysis In Software Reliability Of Component-Based Systems, Sunil Kumar Kamavaram May 2004

Uncertainty Analysis In Software Reliability Of Component-Based Systems, Sunil Kumar Kamavaram

Graduate Theses, Dissertations, and Problem Reports (ETD)

Several architecture-based software reliability models were proposed in the past. These models compute the point estimate of system reliability by plugging point estimates of unknown parameters into the model. These models however, discard the uncertainty of the parameters, that is, they do not attempt to answer the question how parameter uncertainties propagate into overall system reliability. Therefore, the traditional way of estimating software reliability by plugging point estimates may not be appropriate. This thesis is focused on uncertainty analysis of architecture-based software reliability models. In particular, we present uncertainty analysis using the following methods: entropy, perturbation theory, method of moments …
