Abstract
Conventional image quality metrics in photography evolved in the context of so called continuous tone images. In electronic imaging there is now an ever increasing need to develop metrics which apply to (output) images which are quantized, as from laser writers or digital halftone schemes. Fortunately the most robust of the conventional metrics are based on or compatible with the concept of the quantized nature of light (input), and extending these to the case where both input and output are by definition discrete is usually straightforward. A survey is given of these metrics, with examples from recent work on laser writer hardcopy.
