چکیده

Different models for computing the spatial relations have been developed in the last decade. Separate methods are used for computing topological, directional and distance relations. These models have also been extended in fuzzy domains based on fuzzy or vague objects and less attention has been paid to fuzzy relations. In this paper 8 fuzzy topological relations are computed with the help of 1D Allen relations and directional relations are evaluated by using fuzzy membership functions. A matrix of fuzzy relations is developed which provides complete set of information about a 2D scene. This method deals with two types of fuzziness (i) fuzziness involved in the objects position (ii) fuzziness about directional relations.

Spatial Relations Analysis by Using Fuzzy Operators

Spatial relations play important role in computer vision, scene analysis, geographic information systems (GIS) and content based image retrieval. Analyzing spatial relations by Force histogram was introduced by Miyajima et al [10] and largely developed by Matsakis [12] who used a quantitative representation of relative position between 2D objects. Fuzzy Allen relations are used to define the fu...

Fuzzy Spatial Relations for High Resolution Remote Sensing Image Analysis: The Case of "To Go Across"

High resolution remote sensing (HR RS) images allow discriminating between different objects in a scene. Spatial reasoning techniques can be used to interpret and describe the scene. One component of spatial reasoning deals with the modeling and assesment of spatial relations among objects. In this work we propose three models that seize the semantics of the spatial relations “to go across” and...

Combinational Reasoning of Quantitative Fuzzy Topological Relations for Simple Fuzzy Regions

In recent years, formalization and reasoning of topological relations have become a hot topic as a means to generate knowledge about the relations between spatial objects at the conceptual and geometrical levels. These mechanisms have been widely used in spatial data query, spatial data mining, evaluation of equivalence and similarity in a spatial scene, as well as for consistency assessment of...

مدل‌سازی روابط توپولوژیک سه بعدی فازی در محیط GIS

Nowadays, geospatial information systems (GIS) are widely used to solve different spatial problems based on various types of fundamental data: spatial, temporal, attribute and topological relations. Topological relations are the most important part of GIS which distinguish it from the other kinds of information technologies. One of the important mechanisms for representing topological relations...

Quantitative analysis of properties and spatial relations of fuzzy image regions

Properties of objects and spatial relations between objects play an important role in rulebased approaches for high-level vision. The partial presence or absence of such properties and relationships can supply both positive and negative evidence for region labeling hypotheses. Similarly, fuzzy labeling of a region can generate new hypotheses pertaining to the properties of the region, its relat...
