THE ROLE OF EDGE INFORMATION TO ESTIMATE THE PERCEIVED UTILITY OF NATURAL IMAGES

In the quality assessment task, observers evaluate a natura l image based on its perceptual resemblance to a reference. For the u tility assessment task, observers evaluate the usefulness of a nat ur l image as a surrogate for a reference. Humans are willing to use t he information captured by an imaging system and tolerate dist ort ons as long as the underlying task is performed reliably. Conven tional notions of perceived quality cannot generally predict the p erceived utility of a natural image. Many estimators have been design ed to estimate perceived quality scores, and a recent estimator, refe red to as the natural image contour evaluation (NICE), has been dev eloped to estimate perceived utility scores. An analysis of edge in formation in natural images drives object recognition mechanisms in t he human visual system, so this paper examines the role of an edgebased analysis in both popular objective quality estimators and N ICE for estimating the perceived quality or utility of distorted na tur l images. Among the estimators evaluated, results show that est imators that emphasize an edge-based analysis provide the most accu rate estimates of perceived utility scores. Estimators that aug ment the edge-based analysis with an energy-based analysis provide the most accurate estimates of perceived quality scores.
