virtual bool cv::LMSolver::Callback::compute ( InputArray  param,
OutputArray  err,
OutputArray  J 
) const
pure virtual

computes error and Jacobian for the specified vector of parameters

paramthe current vector of parameters
erroutput vector of errors: err_i = actual_f_i - ideal_f_i
Joutput Jacobian: J_ij = d(ideal_f_i)/d(param_j)

when J=noArray(), it means that it does not need to be computed. Dimensionality of error vector and param vector can be different. The callback should explicitly allocate (with "create" method) each output array (unless it's noArray()).
