This implies a mapping of structured semantic information (symbols) to discrete noisy two-dimensional information (digital image). One way of solving this ill-posed problem is to fuse results in different images which have been produced from a single image by smoothing it with various degree. The smoothing reduces noise, but also changes the scale of the image, i.e. features are suppressed. From a theoretical point of view the following questions arise: How can the abstraction of the descri..
A New Approach For Line Extraction and its Integration in a Multi-Scale, Multi-Abstraction-Level Road Extraction System
No full textion-Level Road Extraction System Helmut Mayer and Carsten Steger Lehrstuhl fur Photogrammetrie und Fernerkundung Technische Universitat Munchen Arcisstraße 21, 80290 Munchen, Germany e-mail: [email protected] Lehrstuhl fur Bildanalyse und wissensbasierte Systeme Technische Universitat Munchen Orleansstraße 34, 81667 Munchen, Germany e-mail: [email protected] Abstract: Road extraction is an active area of research. Because roads are elongated objects they can be described symbolically by means of lines. This paper shows, theoretically as well as in practice, why and under which circumstances lines extracted from an image are an abstract representation of roads. Especially the importance of scale is emphasized and the connection between multiple scales and multiple abstraction levels by means of so-called scale-space events is derived. The investigations are based on a sophisticated model for line extraction for which the scales where events occur can be..
From Helmut Jürgensen’s former students: The game of informatics
No full textPersonal reflections are given on being students of Helmut Jürgensen. Then, we attempt
to address his hypothesis that informatics follows trend-like behaviours through the
use of a content analysis of university job advertisements, and then via simulation
techniques from the area of quantitative economics

HELMUT E. LUCK JAKO HISTORYK PSYCHOLOGII
No full textThe article presents the figure of Helmut E. Luck, well-known scientist in the world of historians of psychology. Helmut E. Luck also is well-known in Poland, as the author or the scientific editor of several books in the field of history of psychology. In the first part of the article the short presentation of his scientific career and his scientific achievements are demonstrated. The second part comprises the analysis of his opinions in the scope of social psychology. Helmut E. Luck was the one of pioneers in psychology, who paid attention to social positive phenomena or social positive behaviors. In the field of history of psychology, H.E.Luck made the contribution to methodological analysis of psychological ideas in history, preferring the model which underlines connection of psychology with culture and at the same time creates the opportunity to analysis of biographical plots. The article also shows unquestionable and unusually merits of Luck’s in popularization of knowledge about history of psychology.The article presents the figure of Helmut E.
