In this paper we describe how a group of agents can commonly estimate the position of objects. Furthermore we will show how these modeled object positions can be used for an improved self localization. Modeling of moving objects is commonly done by a single agent and in a robo-centric coordinate frame because this information is sufficient for most low level robot control and it is independent ...

From the perspective of cognitive informatics (CI), this paper proposes internal relations between distance and orientation knowledge of extended objects, and presents a formal representation of spatial knowledge. The connection relation is taken as primitive. Notions of near extension regions and the nearer predicate are developed. Distance relations between extended objects are understood as ...

The localization of an object within a certain environment requires the selection of an appropriate reference object and the establishment of adequate spatial relations between the objects. The decision, which reference object to choose, demands consideration of all applicable spatial relations, which therefore have to be computed before the nal decision can be made. However, the calculation of...

The semantics of spatial relations have been intensively studied in linguistics, psychology, and cognitive neuroscience. Angle, distance, and shape are widely considered to be the key factors when establishing spatial relations. In this work an empirical study shows that previous theories overemphasize variation and we clarify the interdependencies between angle, distance, and shape with respec...

Concept of combined extraction of topological and directional relations information developed by J. Malki et al. [1] by employing the Allen’s temporal relations in 1D spatial domain was improved by Matsakis and Nikitenko [2]. This latter algorithm has high computational complexity due to its limitations of object approximation and segment fuzzification. In this paper, fuzzy Allen relations are ...

The aim of this study was to investigate the association between object relations and emotional processing deficits among a general sample of psychiatric outpatients. The sample consisted of 104 patients consecutively referred to 2 outpatient clinics. Participants completed measures of object relations, emotional processing deficits, and general psychiatric distress. After controlling for the e...
