Customizing MPEG Video Compression Algorithms to Specific Application Domains: The Case of Highway Monitoring
نویسندگان
چکیده
This paper describes the design of a MPEG coding algorithm targeted to compress video sequences generated by highway surveillance cameras. The physical constraints of vehicles as well as the geometry of the highway environment projected into the camera determine a relevant base of a-priori knowledge, which allows obtaining considerable processing speed up as well as higher compression ratio. This paper models the highway environment in terms of rules and shows how a a customized MPEG coding algorithm can take advantage of such rules to improve processing speed and compression ratio.

A New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
