Abstract
A single-valued index, relative contrast sensitivity (RCS), was developed
to quantitatively evaluate color break-up (CBU) phenomenon. The sensibility
of CBU fringe was hypothesized to strongly correlate with RCS, which was
defined as the integrated difference of the opponent-color signals filtered
by spatial contrast sensitivity functions. Psychometric experiments, based
on methods of category scaling and adjustment respectively, were conducted
to examine the proposed numerical metric. The results showed that the
maximal correlation coefficient was as high as 98.9% between the subjective
judgments and the computed numerical values of current experimental results.
A useful application of RCS index was demonstrated by the evaluation of four
driving schemes for CBU suppression.
