Abstract: MPEG4 is an ISO/IEC standard developed by moving picture experts group (MPEG). The standard video MPEG-4 visual (part 2) introduces the notion of video objects (VO). Basically, the concept of the MPEG-4 compression relies on contents. On the other hand, the standard MPEG-4 AVC/H.264 (part 10) relies on the same architecture used in MPEG-2, which does not introduce the concept of video objects. The performances of these video coders depend mainly on motion estimation. The objective of this work is to conceive a codec based on standard MPEG-4 AVC introducing the concept of video objects from an AVC codec, while being based on many motion estimating techniques. This is done with the hope of reaching the highest reduction of the execution time by keeping the best possible precision in order to be able to integrate it in remote monitoring system.
Keywords: motion estimation; real-time MPEG-4 AVC; object-based MPEG-4; remote monitoring; real-time compression; video compression; video objects.
