Paper Abstract

The issue of accurate color reproduction is a hot topic, which is closely linked to the problem of accurate measurement of the human visual threshold, or "Just Noticeable Difference" (JND). Since most imaging scientists believe that JND experiments are too complicated and costly, "Visual Difference" (dV) experiments have gained high popularity. Typically the results of dV experiments are extended in place of JND, and many scientists interchange dV for JND. For example, the current standard color difference formula CIE DE 2000 was constructed on a dataset from dV experiments. However, in order for the "dV to JND" transition to be correct, several assumptions are taken, and whose haven't actually been proven. This paper proposes a relatively inexpensive experiment that will allow a precise JND measurement experiment, which in turn will let verify the assumptions for the dV to JND transition, and perhaps offer a better dataset for development of a more robust and solid color difference formula.
