This paper explores numerical techniques for comparing real and synthetic luminance images. We introduce components of a perceptually based metric using ideas from the image compression literature. We apply a series of metrics to a set of real and synthetic images, and discuss their performance. FinaIly, we conclude with suggestions for future work in formulating image metrics and incorporating them into new image synthesis methods.
