Abstract

A study was conducted on the quantitative evaluation of mura based on visual analysis, intending to clarify the detection method and create an automated mura inspection process. As such, an algorithm to extract was developed and evaluated mura by using a hardware system based on a commercially available CCD camera and a PC with an image processor board. This system can successfully identify and evaluate mura. This paper describes the research in human perception and the approach adapting the intrinsic rules of sensory analysis to the quantitative evaluation of mura.
