Challenges on Video Processing Techniques in Smart City Systems

Date: 23 December 2014
Speaker: Prof. Gao Wen


Video processing plays a critical role in smart city video surveillance systems. Video surveillance systems have been installed in many cities in China, however they are faced with the challenges of “difficult to store large volume of data, hard to find the targeted data and poor quality of images”. New generation of intelligent video surveillance systems is proposed to solve the problems. In particular, efficient video coding algorithms are designed to store large volume of video data; real-time feature extraction and cross-stream search techniques are proposed to facilitate the search of images; resolution improvement and image compensation technologies are developed to improve image qualities. With IEEE1857 as a standard of reference, this seminar will present possible solutions of the challenging issues and discuss the perspectives of the future development in the field.
