Graph-based Data Fusion of Pedometer and WiFi Measurements for Mobile Indoor Positioning

At ACM UbiComp 2014, we propose a graph-based, low-complexity sensor fusion approach for ubiquitous pedestrian indoor positioning using mobile devices. We employ our fusion technique to combine relative motion information based on step detection with WiFi signal strength measurements. The … Continue reading

Camera-Based Indoor Positioning Using Scalable Streaming Of Compressed Binary Image Signatures

At ICIP 2014, we present a novel approach for client-server-based visual localization:┬áRecent progress in the field of content-based image retrieval has enabled camera-based indoor positioning. The matching of smartphone recordings with a database of geo-referenced images allows for meter accurate … Continue reading
