Abstract

A mura quantification method in the mura inspection is reported. Mura is local unevenness of lightness in a uniformly manufactured surface without clear contour which gives viewers unpleasant sensation. The mura has been inspected by human inspectors, however, a measurement to quantify the mura strength is expected. We report a method using multilevel sliced images, which gives an index to evaluate the mura intensity.
