Bk. Jang et Rt. Chin, ON THE INVERTIBILITY OF MORPHOLOGICAL REPRESENTATION OF BINARY IMAGES- COMMENTS, IEEE transactions on image processing, 5(3), 1996, pp. 529-531
In a recent paper, Charif-Chefchaouni and Schonfeld investigated the i
nvertibility of a morphological representation of binary images and de
termined the necessary and sufficient conditions for its inverse. In t
his correspondence, we show that one of the derived necessary conditio
ns is not valid. A counterexample is given to illustrate our observati
on.
