RT Journal Article T1 Colorimetric matching by minimum-square-error fitting A1 Quiroga Mellado, Juan Antonio A1 Alonso Fernández, José A1 Zoido, J. A1 Bernabeu Martínez, Eusebio AB Least-squares approximation can be used in image-based colorimetry once the set of sampling functions is selected. We discuss the accuracy obtained in earlier research, and we compare it with a better calculation method.
