Fuzzy Spatio-temporal Relations Analysis

There are different families of Spatio-temporal relations such as same-place same-time, same-place different-times, for road networks like overtake, derive beside and many others. These relations describe the relative positions of objects in a spatial scene. In existing techniques, these relations are defined qualitatively. Due to imprecise knowledge information and compensation power to small errors, fuzzy methods are becoming more important. In this paper, fuzzy spatio-temporal relations same-place different-time and different-place different time are introduced. To define these relations, histograms of fuzzy Allen relations and fuzzy dissimilarity measure are used.
