Acanthosis Nigricans

Acanthosis Nigricans (AN) is a condition which has been shown to be an early sign of pre-diabetes due to hyper-inslulinemia. However, it is often misconstrued as a sign of uncleanliness, rather than illness. Its characterization by grading is semi-quantitative, subjective and requires extensive training. We demonstrate a new method of AN screening through computer-aided pixel analysis, which is layman-friendly, quantifiable and shows high reproducibility.

If your machine does not have java, which is required to run the application, you can download it at Free Java Download.
