function landmark = perform_farthest_landmark_sampling( W, landmark, DL_landmark, base_points, DL_base, nbr_points )

% perform_farthest_landmark_sampling - samples landmark using least error seeding strategy
%
% points = perform_farthest_landmark_sampling( W, points, nbr_points, DL, base_points );
%
%   points can be []
%   DL is the distance map to base_points, wich is a 2 x p matrix
