Machine Vision Applications in Industrial Inspection XIV
We propose a method to detect defects due to spatially non-uniform brightness on LCD panels by using a machine vision technique. The detection method is based on human vision so that proper subjective assessment experiments were conducted to investigate the correlation between the parameters related to non-uniformity and the degree how easily observable it is. The visibility of the defects reveals to depend mainly on the spatial gradient of brightness variation. Thus, in the proposed method,doi:10.1117/12.650500 fatcat:gufre6joqjfmvcb7alnkfpudiy
