Fuzzy sets for image processing and understanding: introduction
Since the introduction of fuzzy sets [158], this theory was rapidly exploited and further developed for image processing and image understanding problems. One of the reasons is that it is of major interest for dealing with imprecise information and knowledge, and provides a consistent mathematical framework for knowledge representation, information modeling at different levels, fusion of heterogeneous information, reasoning and decision making. In this paper, we will summarize the main research lines and point some new areas that deserve to be investigated. Some references are given as examples, and by far do not aim at being exhaustive.
