The monograph on István Széchenyi presents the Slovenian territory with a story about an extremely important Hungarian politician, economist, and national awakener. As in other nations, it was also ...in Hungary that the long nineteenth century brought to the fore prominent individuals who contributed towards the development of modern national consciousness. Although the Slovenes are probably more familiar with the name of the Hungarian politician Lajos Kossuth, István Széchenyi figured as an equally prominent driver of Hungarian national development. Just how significant his influence was on Hungarian history was demonstrated by none other than Kossuth, his political opponent, who described him as the “Greatest Hungarian”. The volume at hand was compiled by four historians, three Slovenian and one Hungarian. Its central part comprises chapters on Széchenyi’s life, political career, and economic activities, whereas the introductory chapter on the Széchenyi noble family and its estates in the Slovenian territory and the last chapter on relations between the Hungarians and Emperor Franz Joseph embed the monograph within a broader time-span, thus enabling a better understanding of István Széchenyi’s endeavours and his lasting impact on Hungarian history.
The first Habsburg estates in Carniola were part of territorial acquisitions in eastern Alpine lands that the ascending dynasty obtained in the war with King Ottokar II of Bohemia towards the end of ...the thirteenth century and then gradually expanded. Even though the Habsburg dynastic territory had by the 1380s covered almost the entire Carniola, the economic base (landed property, which provided the provincial prince with regular income) was considerably limited. A sizeable portion of the territory was burdened by fiefs and pledges. The redemption of one of the vastest sets of pledged estates in the mid-1430s led to the emergence of account books for the following Carniolan fiscal properties: Kamnik, Gamberk, Goričane, Ig, Višnja Gora, Štatenberk, Novo mesto, Kostanjevica with offices Raka and Vivodina, Pazin, Završje, and Vranja. The account books serve as an extraordinary source for the economic history of the late Middle Ages, by also reflecting the turbulent period of the Habsburg European-wide ascendancy and Frederick’s war with the Counts of Celje. The volume constitutes a critical edition of the account books, with the accompanying discussion in the field of property, administrative and political history.
Zusammenfassung
Während matte Objekte visuell gut erkannt und mit Robotern gegriffen werden können, stellen transparente Objekte neue Herausforderungen dar. So liefern moderne Farb- und ...Tiefenbildkameras (RGB-D) keine korrekten Tiefendaten, sondern verzerrte Abbildungen des Hintergrunds. Wir zeigen in diesem Beitrag, welche Methoden geeignet sind, um nur in Farbbildern transparente Objekte zu erkennen und deren Pose zu bestimmen. Mittels eines Robotersystems werden Ansichten des Zielobjekts generiert und annotiert, um Methoden anzulernen und um Daten für die Evaluierung zu erhalten. Wir zeigen auch, dass mittels einer verbesserten Methode zum Einpassen der 3D-Pose eine deutliche Verbesserung der Genauigkeit der Lageschätzung erreicht wird. Dadurch können falsche Erkennungen aussortiert werden und für richtige Erkennungen wird die Genauigkeit der Poseschätzung verbessert. Somit gelingt es, mit einem Roboter transparente Objekte zu greifen.
In this work we establish dense correspondences between an RGB image and a surface-based representation of the human body, a task we refer to as dense human pose estimation. We gather dense ...correspondences for 50K persons appearing in the COCO dataset by introducing an efficient annotation pipeline. We then use our dataset to train CNN-based systems that deliver dense correspondence 'in the wild', namely in the presence of background, occlusions and scale variations. We improve our training set's effectiveness by training an inpainting network that can fill in missing ground truth values and report improvements with respect to the best results that would be achievable in the past. We experiment with fully-convolutional networks and region-based models and observe a superiority of the latter. We further improve accuracy through cascading, obtaining a system that delivers highly-accurate results at multiple frames per second on a single gpu. Supplementary materials, data, code, and videos are provided on the project page http://densepose.org.
Die monokulare erscheinungsbasierte Kopf”-po”-sen”-schät”-zung mittels des optischen Flusses leidet insbesondere bei
großen Kopfdrehungen in die Bildebene hinein aufgrund des sogenannten ...Aperturproblems unter Stabilitätsproblemen. In
dieser Arbeit wird zur Lösung des Problems eine unabhängige Schätzung der Kopfbewegung durch Berechnung einer
projektiven Transformation basierend auf der Registrierung stabiler Punkte zwischen aufeinanderfolgenden Frames
bestimmt. Um die Schätzung robuster zu gestalten, wird der optische Fluss mit Hilfe eines bewegungsabhängigen
Regularisierungsterms stabilisiert. Die Auswahl geeigneter Punkte zur Berechnung der Transformation wird im Detail
diskutiert und der Einfluss der bewegungsabhängigen Regularisierung auf die Konditionszahl der Hesse-Matrix sowie auf
die Performanz des Systems untersucht. Die Ergebnisse werden anhand repräsentativer Referenzdatensätze validiert.
We propose a single-shot approach for simultaneously detecting an object in an RGB image and predicting its 6D pose without requiring multiple stages or having to examine multiple hypotheses. Unlike ...a recently proposed single-shot technique for this task 10 that only predicts an approximate 6D pose that must then be refined, ours is accurate enough not to require additional post-processing. As a result, it is much faster - 50 fps on a Titan X (Pascal) GPU - and more suitable for real-time processing. The key component of our method is a new CNN architecture inspired by 27, 28 that directly predicts the 2D image locations of the projected vertices of the object's 3D bounding box. The object's 6D pose is then estimated using a PnP algorithm. For single object and multiple object pose estimation on the LINEMOD and OCCLUSION datasets, our approach substantially outperforms other recent CNN-based approaches 10, 25 when they are all used without postprocessing. During post-processing, a pose refinement step can be used to boost the accuracy of these two methods, but at 10 fps or less, they are much slower than our method.
Zusammenfassung
Der Plastik‐Index (PLIX) bietet Konsumierenden und Unternehmen ein verständliches Instrument zur Bewertung von Kunststoffverpackungen und zum Vergleich von Kunststoffverpackungen. Der ...PLIX befähigt Konsumierende, ihren Verpackungsverbrauch zu reduzieren und Unternehmen in Handel und Logistik, ihren gesamten ökologischen Fußabdruck zu minimieren. Die Bewertungskriterien für den PLIX sind die Verpackungsmenge, die Rezyklierfähigkeit und deren Umweltwirkung; die daraus resultierende Bewertung wird in einem „best case“ bis „worst case“ Szenario dargestellt. Unter Berücksichtigung des Lebenszyklusgedankens wird die Verpackung von „Cradle to Gate“, also vom Rohstoffabbau bis zum Point of Sale im Einzelhandel berücksichtigt. In der vorliegenden Fallstudie dient der PLIX als Instrument zum Vergleich verschiedener Verpackungen innerhalb der Produktgruppe Tomaten. Grundsätzlich ist der PLIX jedoch auch für Anwendungsfälle außerhalb des Lebensmittelbereiches geeignet.
Summary
The Plastic‐Index (PLIX) offers consumers and companies a user‐friendly tool to evaluate and compare plastic packaging. The PLIX enables consumers to reduce their packaging consumption, and companies in trade and logistics to minimize their overall environmental footprint. The evaluation criteria for the PLIX are packaging quantity, recyclability, and environmental impact. The resulting assessment is displayed in a best to worst case scenario. Using life cycle thinking, the packaging is accounted from cradle‐to‐gate, from resource extraction to the point of sale in retail. In the present case study the PLIX serves as an instrument to compare different packaging within a product group, for example tomatoes. However, the PLIX can be used to analyze case studies from other industries but food.
