Viewpoint estimation, especially in case of multiple object classes, remains an important and challenging problem. First, objects under different views undergo extreme appearance variations, often making withinclass variance larger than between-class variance. Second, obtaining precise ground truth for real-world images, necessary for training supervised viewpoint estimation models, is extremel...

In this article the authors consider the interplay between conflict and globalization, arguing that the interaction between globalization and conflict is complex. While much has been written on how globalization generates or accentuates conflict little has been written on how conflict and globalization interact to produce both positive and negative results.

While virtual environments in interactive entertainment become more and more lifelike and sophisticated, traditional media like television and video have not yet embraced the new possibilities provided by the rapidly advancing processing power. In particular, they remain as non-interactive as ever, and do not allow the viewer to change the camera perspective to his liking. The goal of this work...

This paper proposes a "non-contact virtual clay modeling interface." We developed a prototype of a three-dimensional modeling system that allows the designer to deform the "virtual clay" by his or her hand movements. In our proposing method, the user's hand movement is observed using multiple cameras to estimate its position and orientation. The virtual clay is modeled by Catmull-Clark subdivis...

The literature in computer vision is rich of works where different types of activities – single actions, two persons interactions or ego-centric activities, to name a few – have been analyzed. However, traditional methods treat such types of activities separately, while in real settings detecting and recognizing different types of activities simultaneously is necessary. We first design a new un...

During the last years, computer vision tasks like object recognition and localization were rapidly expanded from passive solution approaches to active ones, that is to execute a viewpoint selection algorithm in order to acquire just the most significant views of an arbitrary object. Although fusion of multiple views can already be done reliably, planning is still limited to gathering the next b...

This paper introduces a novel approach for face recognition using multiple face patterns obtained in various views for robot vision. A face pattern may change dramatically due to changes in the relation between the positions of a robot, a subject and light sources. As a robot is not generally able to ascertain such changes by itself, face recognition in robot vision must be robust against varia...

This paper defines viewpoints in order to deal with the integrated network management complexity. A viewpoint leads to the representation of a system with emphasis on a specific concern. Five viewpoints are identified, namely information, functional, communication, architectural and organizational, and then integrated. The network management standards provisions and lacks for every viewpoint ar...
