Non- Contact Colorimeter for Human Tooth Color Assessment Using A Digital Camera

摘要

Wu et al developed model-based and regression-based colorimeters in their paper entitled Imaging colorimetry using a digital camera. They found that the regression-based system worked better than the model-based system. In this work, we modify their regression-based model slightly to improve the system performance. We also present another regression-based model that is capable of recovering the spectral reflectance of teeth. Both models are realized and evaluated clinically.
