From: Comparison and extension of three methods for automated registration of multimodal plant images
Distributions of components of the transformation matrix (\(T_{ij}\)) acquired by registration of FLU/VIS images of Arabidopsis shoots using different methods (FP, PC, INT), different image representations (color-edges—CE, grayscale—GS) and different scaling factors. The \(2\times 2\) submatrix of \(i,j<3\) values describes scaling and rotational components of \(T_{ij}\), while \(T_{13}\) and \(T_{23}\) are the global image translations
