| bool vgl_h_matrix_2d< T >::projective_basis | ( | vcl_vector< vgl_homg_point_2d< T > > const & | four_points | ) |
transformation to projective basis (canonical frame).
Compute the homography that takes the input set of points to the canonical frame. The points act as the projective basis for the canonical coordinate system. In the canonical frame the points have coordinates: ${array}{cccc} p[0] & p[1] & p[2] & p[3] \% 1 & 0 & 0 & 1 \% 0 & 1 & 0 & 1 \% 0 & 0 & 1 & 1 {array}$

| bool vgl_h_matrix_2d< T >::projective_basis | ( | vcl_vector< vgl_homg_line_2d< T > > const & | four_lines | ) |
transformation to projective basis (canonical frame).
Compute the homography that takes the input set of lines to the canonical frame. The lines act as the dual projective basis for the canonical coordinate system. In the canonical frame the lines have equations: x=0; y=0; w=0; x+y+w=0. (The third line is the line at infinity.)
