PhETA: Photograph Edge Transition Analyzer

Current version: 1.1.1 (released Sept. 21, 2007) | change log

PhETA was my MS thesis project, completed in November 2005. The heart of the project is a tool intended to assist users in determining an objective measure of the quality of digital images by analyzing properties of the edge transitions contained in those images.

Abstract: 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.
