Fuzzy Circle: Theoretical Study on Simple Closed Curves
Ying Zhao · 1999
Fuzzy circle,a new concept,was introduced and discussed.If a simple closed curve on the xy plane approximates a crisp circle,then a fuzzy circle of it can be made. Roughtly speaking,a fuzzy circle is formed by a simple closed curve together with a circularity function.A sequence of fuzzy circles for a given simple closed curve can be made,and it can be proof that the sequence of fuzzy circle converges to a crisp circle.
