Abstract: In this paper, we present a geometrical localization method based on a combination of global image features. Our method represents each image by two feature vectors. The first feature...
SVMs for Vibration-based Terrain Classification (2008)
Christian Weiss, Matthias Stark, Andreas Zell
Abstract. When an outdoor mobile robot traverses different types of ground surfaces, different types of vibrations are induced in the body of the robot. These vibrations can be used to learn a...
Markus Kowarschik, Christian Weiss
Abstract. Efficient program execution can only be achieved if the codes respect the hierarchical memory design of the underlying architectures; programs must exploit caches to avoid high latencies...
Abstract. We present an intuitive method to generate visually convincing 3D models of indoor environments from data collected by a single 2D laser range finder and a color camera. The 2D map created...

Distributed shared objects are a well known approach to achieve independence of the memory model for parallel programming. The illusion of shared (global) objects is a convenient abstraction which...
1 Regressive Channel Coding with Sequential Decoding for Embedded Source Coders (2007)
Joachim Hagenauer, Thomas Stockhammer, Christian Weiss
A channel coding system for strongly varying channels (mobile radio, Internet) unknown to the encoder is presented. It matches progressively coded sources (e.g., video, images, audio, speech) with...
Fast Outdoor Robot Localization Using Integral Invariants (2007)
