User generated videos with mobile phone cameras are becoming more and more ubiquitous allowing people to share live content with remote parties, possibly in real-time. However with limited mobile phone capabilities, these videos are usually of small resolution, resulting in a small field of view for acceptable quality. Fortunately with the proliferation of video capture-enabled mobile phones, there is high chance that one or more persons will be shooting the same scene from different views. In this demonstration, we are showing an end-to-end system which receives video streams coming from different mobile phones, time synchronizes the streams and produces a single composite mosaic video, and all of this is done in real-time. The proposed system operates without coordination between users. The system has been tested under various capturing conditions such as indoor, outdoor, day and night conditions.
