  Note: Counsidering a color image, this Matlab code enables to extract: 
            - MaxI_R (resp. MaxI_G, MaxI_B), the gradient magnitude image of the Red (resp. Green, Blue) channel,
            - R_theta_90 (resp. G_theta_90, B_theta_90), the tangent derivative of the Red (resp. Green, Blue) channel  
                                  orthogonal to the gadient of the Red (resp. Green, Blue) channel.
