Extracting or recovering useful information while reducing unwanted noise can be achieved using sophisticated mathematical methods and computation to process signals (audio, video, electromagnetic, biomedical, remote sensing, multimedia and others). Applications include multimedia compression, communications, networked media systems, augmented reality, and remote sensing. In addition to using theoretical analyses and systematic experiments to study the underlying principles, we often build real‐time test beds and prototypes to validate and demonstrate our ideas. Examples include:
- Image and video coding,
- Media streaming,
- Mobile augmented reality,
- Compact descriptors for visual search,
- Personalized and immersive media.
