Abstract
A triage metric is proposed to determine the extent of blocking and contouring artifacts in an image due to JPEG compression. It is found that this metric has a linear correlation with subjective judgements of print quality. This triage metric can be used to determine the amount of needed image enhancement or achieve a good trade-off between image quality and system throughput.
