IST WCAM Project: Smart and Secure Video Coding Based on Content Detection.
2004
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 AudioVisual Seamless Networking" which is presented as well [1]. The main feature of our system is it includes smart 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 good quality 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.
