Abstract

Fuzzy geometric shapes like point, line, circle, ellipse and polygon are defined on 2-D support space. The definitions are based on the level sets of a fuzzy set and it is easy to construct or recognize these fuzzy shapes from their definitions. Complementary shapes such as circular, elliptic and polygonal holes are also defined. A concept of concave fuzzy set is introduced in this connection.
