Abstract
In recent years a number of image fidelity measures have been developed.
These measures are designed to predict a person's ability to
perceive differences between two nearly identical images. Successful image
fidelity measures
allow digital imaging developers to replace difficult and time consuming
subjective evaluations with automated evaluations. Although
a number of image fidelity measures have been developed, no method for
evaluating and comparing the accuracy of
these measures has been commonly accepted. In this paper we describe a new
method for evaluating image fidelity measures.
The method involves comparing spatially localized ratings from a human
subject with distortion maps generated by an image fidelity measure.
