“…On the basis of definitions for simple fuzzy points, line segments and regions, Shi and Liu (2007) provide an example of computing the interior, boundary, and exterior of spatial objects for different values, and the interior, boundary, and exterior of spatial objects were confirmed for each given value. Based on the fuzzy definitions, Liu and Shi (2009) ) of the new 3 3  integration model is the ratio of the area( or volume) of the meet of two fuzzy spatial objects in a join of two simple spatial object(here a join of two fuzzy objects means "union" of two fuzzy objects; a meet of two fuzzy objects means "intersection" of two fuzzy objects (Liu and Shi, 2009)). And it was difficult to change or transform the new 3 3  integration model to describe the topological relations between one simple crisp spatial object and one simple fuzzy spatial object.…”

“…Meanwhile, Liu and Shi (2009) proposed a 3 3 integration model to compute the topological relations between fuzzy line segments, and discovered sixteen topological relations between simple fuzzy region and simple fuzzy line segment. However, the 3 3 integration model could not get the topological relation as shown in figure 13(c).…”

“…A fuzzy subset λ of a fuzzy topological space X is fuzzy C -closed if C λ is fuzzy open in X. Xavier and Thangavelu [12] defined fuzzy C -open sets using the arbitrary complement function C which characterizes fuzzy topological space, fuzzy continuity and fuzzy compactness. The computation of fuzzy interior, closure, boundary and exterior provide many solutions to problems in image processing [3], [10] and spatial objects in GIS [6], [7] [11]. In this paper we define the fuzzy C -interior, fuzzy C -exterior and their properties are investigated.…”
