Project: Visual sensor networks can be characterized by wireless battery-operated sensing nodes that are empowered with sight and are capable of complex visual analysis tasks. Since each node has severe energy constraints, it is imperative to optimize the computation, coding and communication of visual data.




One promising approach is to reverse the conventional compress-then-analyze paradigm. In this case, image features are collected by sensing nodes, processed, and delivered to final destination(s) to enable higher level visual analysis tasks by means of either centralized or distributed classifiers. The MSP (Multimedia Signal Processing) group participates in the GreenEyes (http://www.greeneyesproject.eu/) project, a European Union FP7 FET (Future and Emerging Technologies) project that tackles the encoding and transmission of visual features in resource constrained sensor networks.

The positions available regard the development of novel feature coding schemes to support the joint analyze-and-compress paradigm in visual sensor networks and the demonstration and validation of the results achieved by means of a working prototype on a real wireless sensor node platform. In this context, the techniques for feature extraction and coding must support the energy and bandwidth constraints of the sensing nodes without a significant impact in terms of analysis task efficiency.
