Colorimetrically-based camera characterisation

Alternatively, Spectral Based Camera Characterisation can be used. This can be divided into two measurement of the spectral sensitivities of the camera and recovery of the spectral reflectances. Both will be introduced later. 

There are three methods for colorimetrically characterising a camera, namely  

An example using the least-sqnares method is given here. Suppose the reference target has N colonr samples. A ninth-order polynomial regression is applied to make an empirical transformation model. The equations can be written as  

refer to the camera s raw signals for sample i and Qy are the coefficients to be obtained for the camera characterisation model. 

Since M and V are known, therefore, the coefficient matrix can be determined by the following
