Display Mura Analysis Module for TrueTest™ Software TrueMURA™
Complete analysis system for characterizing display mura in terms of human visual perception Radiant Vision Systems TrueMURA™ Analysis Module is the first commercial system available to provide advanced image analysis algorithms for computing JND ("Just Noticeable Differences"). This augments the Defect Analysis functions already available in TrueTest™ Automated Visual Inspection software. The JND detection algorithm incorporated in TrueMURA™ is based on U. S. patent 7,783,130, "Standard Spatial Observer" technology, licensed by Radiant Vision Systems from the National Aeronautics and Space Administration (NASA). Automation of human judgment of display defects or blemishes (referred to as "mura") is difficult because human visual recognition of uniformity variations and other defects is dependent on many factors including brightness, color, and spatial relationships. To accurately discriminate JND - artifacts just noticeable by a human observer - TrueMURA™ is based on a model of human perception which allows a grading of display mura in a way designed to match human observers, ignoring mura that cannot be seen by humans and ranking different mura which are distinguished by humans into categories matching those assigned by human observers. The TrueMURA module includes these tests, above and beyond those offered in TrueTest Automated Visual Inspection software: Black Mura Blob Analysis Butterfly Mura Corner Light Diagonal Line Mura Edge Mura LED Mura Line Mura Random Mura Spot Mura TrueMURATest
