Discrete Curvature Calculation For Fast Level Set Segmentation
Fast level set methods replace continuous PDEs by a discrete formulation, improving the execution times. The regularization in fast level set methods was so far handled indirectly...

Curvature Guided Level Set Registration Using Adaptive Finite Elements
Abstract. We consider the problem of non-rigid, point-to-point registration of two 3D surfaces. To avoid restrictions on the topology, we represent the surfaces as a level-set of t...

Calibration-free Line-based Tracking for Video Augmentation
This paper presents a calibration-free line-based tracking method to augment virtual objects into a video sequence. The presented method uses a cube on the first image to calibrat...

Recovering height information from SAR images of terrain
In this paper we suggest a new approach for recovering 3-D depth from a field of surface normals. The surface normals are extracted from Synthetic Aperture Radar (SAR) images usin...

A Comparison of PMD-Cameras and Stereo-Vision for the Task of Surface Reconstruction using Patchlets
Recently real-time active 3D range cameras based on time-of-flight technology (PMD) have become available. Those cameras can be considered as a competing technique for stereo-vis...
