PhETA: An Interactive Tool for Analyzing the Quality of Digital Photographs from Edge Transitions
Anthony James Allowatt · 2005
The goal of this thesis is to build an interactive tool for analyzing the quality of a digital image and predicting the scale at which it may be published. Since edges are present almost everywhere in most digital images, we use a mathematical edge model as the basis of analysis. In particular, we are interested in the luminance and chromaticity behavior at edge boundaries. We use this model to develop PhETA – Photograph Edge Transition Analyzer – an interactive tool that allows novice users to view and understand the results gained from this analysis in a clear and simple manner. Acknowledgements I would like to thank my advisor Roger Ehrich for his constant guidance and direction throughout my time on this thesis, and committee members James D. Arthur and Stephen Edwards for their continued support both in and out of class. iii
