| This paper studies connectivity aspects that arise in image operators that process connected components. The focus is on morphological image analysis (i.e., on increasing image operators) and, in particular, on a robustness property satisfied by certain morphological filters that is denominated the strong property. The behavior of alternated compositions of openings and closings is investigated under certain as- sumptions, particularly connectedness and a connected com- ponent preserving condition. It is shown that these condi- tions cannot in general guarantee the strong property of cer- tain connected alternated filters because of issues related to the locality of the filters. As treated in the paper, there have been a series of misunderstandings in the literature concern- ing this topic, and it is important to clarify them. The root cause of those problems is discussed, and a solution is in- dicated. The class of connected openings and closings used to build connected alternated filters should therefore be de- fined to avoid such situations, since the strong property of alternated filters should be a distinctive characteristic of this class. | |
