ICC profiles are the industry standards for transforming color data from electronic devices to and from a common profile connection space. A profile exhibits non-smoothness if it introduces banding and/or discontinuities when transforming a smooth image. Currently, all methods of identifying and reducing profile non-smoothness are manual. The team’s project goal was to develop automatic methods to quantitatively measure, and then correct, non-smoothness in ICC profiles.
