In this work, we investigate the use of a digital camera for colorimetry. Our system consists of a measurement device and a corresponding calibration mapping. The goal is to design a system that will accurately assess the color of a sample. We develop two colorimetry systems by applying model-based and regression-based techniques. For both systems, the measurement device is formed by a digital ...
Fig. 1. Regression analysis (regression line – continuous – and 95% prediction interval – dashed lines) to evaluate commutability of IRMM BCR-304 (triangle) and NIST SRM 956c (black circles) between direct potentiometry and colorimetry assays for serum lithium. Gray circles identify native serum samples. Commutability of two JCTLM-listed secondary reference materials for two commercial lithium ...
