Abstract: In this thesis we investigate the transmission and processing of sensor-rich videos in mobile environment. Our work focuses on the following key issues for sensor-rich videos: 1) Energy-efficient video acquisition and upload. We design a system to support energy-efficient sensor-rich video delivery. 2) Point of Interest (POI) detection and visual distance estimation. We propose a technique which is able to detect interesting regions and objects and their distances from the camera positions in a fully automated way. 3) Presentation of user generated videos. We present a system that provides an integrated solution to present videos based on keyframe extraction and interactive, map-based browsing. 4) Geo-predictive video streaming. We present a method to predict the bandwidth change for HTTP streaming. The method makes use of the geo-location information to build bandwidth maps to facilitate bandwidth prediction, and efficient quality adaptation.
