Member Function Documentation

void projection_lsqf::f (  const vnl_vector< double > &  hv, vnl_vector< double > &  proj_err )  [inline, virtual]

compute the projection error given a set of h parameters. The residuals required by f are the Euclidean x and y coordinate differences between the projected from points and the corresponding to points. Implements vnl_least_squares_function. Definition at line 51 of file vgl_h_matrix_2d_optimize.h.
