Detailed Description

Note

The transformation matrix (A) returned by getTransformMatrix by definition: A * X = R, we have A, so that X = inv(A' * A) * A' * R where A is the set of known reflectances for each component, R is the reflectances of a specific pixel and X is the proportion of each component.
