do prior work for some works that require only valid coordinates
[usage]
[filt_spec] = vb_valid_coordinate_filter_encode(coord)
[input]
coord : <required> coordinate
[output]
filt_spec : filtering specifications
: - valid_coord : valid coordinates
: - org_size : original size of coordinates [Npoint x Ndim]
: - v_coord_idx : index of valid coord in original[N x 1]
