In the first class of approaches, a fundamental property which guides the construction of fuzzy operations is the duality between erosion and dilation. In the second class, the notion of adjunction plays a major role. These two approaches rely on the definition of an inclusion degree between two fuzzy sets, from which the erosion is derived. This degree of inclusion takes different forms in the two approaches. Here we focus on the four basic operations of mathematical morphology ‒ erosion, dilation, opening and closing ‒ from which numerous other operations can be derived. rv:
