A Novel Regression Model From RGB Image Data To Spectroradiometric Correlates Optimized For Tooth Colored Shades

摘要

ObjectivesObjectives of this study were to correlate RGB data from the VITA Linearguide 3D Master and VITA Bleached Guide 3D Master shade guides with their spectroradiometric correlates through a regression model while indicating a methodology for validation of accuracy of digital imaging systems. Additional objectives were to provide summary RGB data and to determine a relationship between lightness and RGB values for these shade guides.
