A comparison of characteristic features of the labelled objects in a selected corneal deformation image. a The image \(L_{\text{O}} \left( {m,n} \right)\) after labelling objects. Elements described by particular labels were assigned colours from the artificial colour map. The index of 1 corresponds to the area of the cornea. b A graph showing major axis lengths of the labelled objects. The largest parameter value belongs to the object with the label 1 (this area corresponds to the cornea). c A graph showing surface areas of the labelled objects. The highest parameter value belongs to the object with the label 8 (this area does not represent the cornea)
