Artykuł opisuje kluczowe grupy produktowe wprowadzone do oferty firmy w okresie ostatnich 20 lat. Krótko charakteryzuje przyczyny ich powstania oraz cele związane z ich zastosowaniem na rynku górniczym. Rozwój wyrobów przedstawiony jest na tle rozwoju całej branży górniczej.
When driving at night, it is difficult to detect obstacles such as pedestrian and wild animals on the opposite lane which is out of sight. Adaptive front lighting system (AFS) can be used to avoid accidents with obstacles that are difficult to detect with a conventional lighting system. The basic concept of AFS is to collect the information such as vehicle speed, yaw rate, steering angle, suspension...
Here an efficient fusion technique for automatic face recognition has been presented. Fusion of visual and thermal images has been done to take the advantages of thermal images as well as visual images. By employing fusion a new image can be obtained, which provides the most detailed, reliable, and discriminating information. In this method fused images are generated using visual and thermal face...
When the traditional CANNY algorithm is applied for edge detection, thresholds are needed to filter candidate edge points after non-maximal suppression. But at present, thresholds are set by experience and the optimal choice is obtained by repeated tests and comparisons. In addition, the choice of current thresholds does not take characteristics of uneven lighting images into account. In some special...
This paper presents a projection model to fuse the scores of a visual face verification system and an infrared face verification system. Essentially, the model consists of an arbitrarily number of linear projection vectors with randomly permuted elements. An equal error rate formulation is next adopted to learn the linear coefficients for projection. The learned model is consequently used for prediction...
GIGA (the Advanced Computer Graphics Group from the University of Zaragoza) has developed two packages, code-named ALEPH and SICARA3D. Those systems are capable of both calculating light distribution in complex environments, based on a rigorous simulation of the physical phenomena involved, and visualizing the results in a photorealistic way, including models of the HVS (human visual system) implemented...
W referacie przedstawiono ważniejsze wnioski powstałe w oparciu o doświadczenia zebrane w trakcie prowadzonych obliczeń oświetleniowych z wykorzystaniem programów graficznych. Omówiono ograniczenia komputerowego modelowania kształtu geometrycznego wybranych obiektów architektonicznych oraz stanu powierzchni elewacji. Zasadnicza część pracy zawiera prezentację sposobów praktycznego wykorzystania modeli...
