Abstract:

Modern developments in sensor technology, signal processing, and wireless communications have enabled the conception and deployment of large-scale networked sensing systems spanning numerous collection platforms and varied modalities. These systems have the potential to make intelligent decisions by integrating information from massive amounts of sensor data. Before such benefits can be achieved, significant advances must be made in methods for communicating, fusing, and processing this evergrowing volume of diverse data. In this one-year research project, we aimed to expose the fundamental issues and pave the way for further careful study of compressive approaches to video acquisition, fusion, and processing. In doing so, we developed a theoretical definition of video temporal bandwidth and applied the theory to compressive sampling and reconstruction. We created a new framework for compressive video sensing based on linear dynamical systems, lowering the compressive measurement rate. Finally, we applied our own joint manifold model to a variety of relevant image processing problems, demonstrating the models effectiveness and ability to overcome noise and occlusion obstacles. We also showed how joint manifold models can discover an objects trajectory, an important step towards video fusion.
