Baessler, Bettina; Schaarschmidt, Frank; Stehning, Christian; Schnackenburg, Bernhard; Maintz, David; Bunck, Alexander C. (London : Biomed Central Ltd., 2015-08-01)

Background: The aim of this study was the evaluation of a fast Gradient Spin Echo Technique (GraSE) for cardiac T2-mapping, combining a robust estimation of T2 relaxation times with short acquisition times. The sequence ...
Multitemporal crop type classification using conditional random fields and rapideye data

Hoberg, Thorsten; Müller, Sören (Göttingen : Copernicus GmbH, 2011)

The task of crop type classification with multitemporal imagery is nowadays often done applying classifiers that are originally developed for single images like support vector machines (SVM). These approaches do not model ...
Multitemporal quality assessment of grassland and cropland objects of a topographic dataset

Helmholz, Petra; Büschenfeld, Torsten; Breitkopf, Uwe; Müller, Sören; Rottensteiner, Franz (Göttingen : Copernicus GmbH, 2012)

As a consequence of the wide-spread application of digital geo-data in geographic information systems (GIS), quality control has become increasingly important to enhance the usefulness of the data. For economic reasons a ...
