Introduction to the Special Issue on 'Recent advances on analysis and processing for distributed video systems'

摘要

Distributed video systems are of increasing importance in many applications, including surveillance, healthcare, entertainment, and unmanned area monitoring. With the rapid growth of demand for ubiquitous sensing and service, great challenges have been raised for analyzing, transmitting, processing, and displaying the massive video data from distributed sources. As such, evolution is changing from the static centric-based processing to the dynamic collaborative computing and processing among distributed video processing nodes. And this evolution, in turn, is issuing new challenges in front of us. For example, how to efficiently allocate the resources among distributed video processing nodes for achieving optimized performance? How to effectively identify and locate objects that are moving across multiple video sensors? How to estimate the overall statistics based on the collaborative analysis from distributed video processing nodes? How to visualize the distributed massive data for a more convenient human operating? These new challenges require us to extending the existing approaches or exploring new suitable techniques.
