ABSTRACT This paper proposes an integrated solution for smart delivery of video surveillance data. The system is developed within the IST project WCAM "Wireless Cameras and Audio- Visual Seamless Networking" which is presented as well (1). The main feature of our system is it i ncludes s mart video coding based on automatic scene analysis and understanding. Specifically, the segmentation results are used for encoding regions of interest (ROI) in Motion JPEG 2000 guarantying goo d qu ality for the semantically relevant objects while keeping a low average data rate. Evaluation of different strategies for JPEG 2000 ROI encoding based on segmentation is presented. We propose a ROI coding strategy optimising the overall quality of the frames while keeping the average data rate low enough for wireless video transmission.
