In the paper the system based on camera and multimedia projector enabling a user to control computer applications by dynamic hand gestures is presented. The main objective is to present the gesture recognition methodology which bases on representing hand movement trajectory by motion vectors analyzed using fuzzy rule-based inference. The approach was engineered in the system developed with J2SE...

In this paper we will introduce a measure of interactivity between marginal distributions of a joint possibility distribution C as the expected value of the interactivity relation between the γ-level sets of its marginal distributions.

With the rapid development of e-commerce, there is an immediate need for an autonomous and robust system that can offer decision-making support for customers who are looking for the cheapest, the most familiar, or the best-quality product. This paper presents an agent-based web-mining approach to Internet shopping. In contrast to the traditional multiagent systems, which use rule-based or case-...

Object-oriented classification has shown a great potential in the classification of very high resolution satellite images, such as QuickBird and Ikonos. In the object-oriented classification, object segmentation is a crucial process and it significantly influences the classification results. Current techniques heavily rely on the operator’s experience to find appropriate segmentation parameters...

in the course of the present study, the results of parametric approach are compared with those obtained through fuzzy approach using ahp as well as multivariate regression methods for comparisons and investigating the efficiency of the fuzzy method as applied in land suitability assessments. the correlation coefficients between land index and observed yield in the study area through fuzzy appro...

This paper proposes a formal approach of constructing shared mental models between computational improvisational agents (improv agents) and human interactors based on our socio-cognitive studies of human improvisers. Creating shared mental models helps improv agents co-create stories with each other and interactors in real-time interactive narrative experiences. The approach described here allo...

A novel supply chain operational transport planning model is developed in this paper. The goals of the model are to minimize the number of used trucks and the total inventory levels. Because of somewhat imprecise nature of vehicle capacities and decision makers’ aspiration levels for the goals, a fuzzy multiobjective linear programming (FMOLP) modeling approach is adopted. Moreover, an interact...

In this paper, a new approach is presented to fit arobust fuzzy regression model based on some fuzzy quantities. Inthis approach, we first introduce a new distance between two fuzzynumbers using the kernel function, and then, based on the leastsquares method, the parameters of fuzzy regression model isestimated. The proposed approach has a suitable performance to<b...
