Abstract
Comments are made on the above named work by V. Lacroix (see
ibid., vol.10, no.6, p.803-10, 1988). The commenters contend that the
proposed orthogonal bases are the same as the edge subspace bases in the
approach of W. Frei and C.C. Chen (IEEE Trans. Comput., vol.C-26, no.10,
p.988-98, 1977) and that the ratio for detecting edges is the same as
that proposed by Frei and Chen for special cases. In his reply, Lacroix
explains the relationship between his method and that of Frei and Chen
