Warping (Franz et al., 1998b) and 2Dwarping (Möller, 2009) are effective visual homing methods which can be applied for navigation in topological maps. This paper presents several improvements of 2D-warping and introduces two novel “free” warping methods in the same framework. The free warping methods partially lift the assumption of the original warping method that all landmarks have the same ...

The finite element method is employed for the flexural-torsional linear buckling analysis of beams of arbitrarily shaped composite cross-section taking into account generalized warping (shear lag effects due to both flexure and torsion). The contacting materials, that constitute the composite cross section, may include a finite number of holes. A compressive axial load is applied to the beam. The...

Style transfer of an image has been receiving attention from the scientific community since its inception in 2015. This topic is characterized by accelerated process innovation; it defined techniques that blend content and style, first covering only textural details, subsequently incorporating compositional features. The results such had a significant impact on our understanding inner workings ...

From 18.04.04 to 23.04.04, the Dagstuhl Seminar 04172 Perspectives Workshop: Visualization and Image Processing of Tensor Fields was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar...

The homogeneous representation for points provides a consistent notation for affine and projective mappings. Homogeneous notation was used in projective geometry [Maxwell46], [Coxeter78] long before its introduction to computer graphics [Roberts66]. The homogeneous notation is often misunderstood so we will take a moment to clarify its use and properties. In familiar Euclidean geometry we repre...

The main objective of this thesis is to study new methods for estimating the macro velocity model, which controls the wave kinematics, in the context of reflection seismology. Migration velocity analysis evaluates the quality of the velocity model used for imaging seismic data by comparing images of the subsurface structures as a function of extension parameters, such as offset, reflection angl...
