The authors propose a framework to encrypt Baseline JPEG files directly at bitstream level, i.e., without the need to recompress them. The authors' approach enables encrypting more than 25 pictures per second in VGA resolution, allowing real-time operation in typical video surveillance applications. In addition, their approach preserves the length...
Cross-Virtuality Visualization, Interaction and Collaboration
In X-Pro, we investigate novel user-centric methods and techniques for cross-virtuality analytics. Cross-virtuality analytics in our sense aims to enable a seamless integration and transition between conventional 2D visualization, augmented reality and virtual reality in order to provide users with optimal visual and algorithmic support with maximum cognitive and perceptual...
