This work discusses Ann Cavoukian's fourth Privacy by Design (PbD) principle, which is known as Full Functionality PositiveSum, not Zero-Sum. The authors argue that this principle regulating trade-o s between privacy and functionality is questionable from a theoretic as well as from an operational point of view. A more consistent and pragmatic de nition of positive-sum privacy is proposed and d...

Integration of huge IT applications is one of the most important IT challenges companies are faced to enable the efficient execution of business processes. There was no standardized procedure how integration landscapes could be designed and specified on the one hand. And, on the other hand, no continuous method exists to transform those in most cases abstract architectures into executable syste...

This manuscript presents an efficient approach to map pedestrian surveillance footage to an aerial view for global assessment of features. The analysis of the footages relies on low level computer vision and enable real-time surveillance. While we neglect object tracking, we introduce cumulative grids on top view scene flow visualization to highlight situations of interest in the footage. Our a...

In a typical video surveillance framework, a single camera or a set of cameras monitor a scene in which human activities are carried out. In this paper, we propose a complementary framework where human activities can be analyzed under a subjective point of view. The idea is to represent the focus of attention of a person in the form of a 3D view frustum, and to insert it in a 3D representation ...

This paper presents Sakbot, a system for moving object detection in traffic monitoring and video surveillance applications. The system is endowed with robust and efficient detection techniques, which main features are the statistical and knowledge-based background update and the use of HSV color information for shadow suppression. Tracking is provided by a symbolic reasoning module allowing fle...

We study the time-evolution of the joint and the conditional probability of macroscopic variables of a closed system from a microscopic point of view. We derive an exact generalized master equation for their time rate of change which consists of two parts, one instantaneous and local in state space, the other retarded and nonlocal in state space. It is represented by stochastic operators depend...

We consider the problems of finding and determiningcertain query answers and of determining containmentbetween queries; each problem is formulated in pres-ence of materialized views and dependencies under theclosed-world assumption. We show a tight relation-ship between the problems in this setting. Further,we introduce algorithms for solving each problem forthose in...

introduction this study is dealt with the environmental planning from a bio-cybernetic and hierarchical systems viewpoint within the context of landscape ecology. this viewpoint requires not only knowledge of the science of ecology but also ecological wisdom in order to recognize the place of humankind in nature. the conceptual and practical approach which is provided will help landscape planne...
