Radiant Vision Systems TrueMURA™ Display Mura Analysis Software TrueMURA™

Description
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, "Spatial Standard 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 Software license provides several mura tests in addition to what is offered in standard TrueTest Software. TrueMURA allows users to define a complete set of measurement parameters and set pass/fail criteria for different types, locations, and severities of mura in an image. The software license includes specific tests for identification and measurement of mura types including: Black Mura Blob Analysis Butterfly Mura Corner Light Diagonal Line Mura Edge Mura LED Mura Line Mura Spot Mura TrueMURATest
