Embedded system implementation of scalable and object-based video coding

Embedded system architecture, which call be used for scalable and object-based video coding, is discussed in this paper. As for scalable video coding, namely JPEG2000, design framework for system architecture is Constructed with the main theme focused oil the ability of exploring implementation scheme for each process of JPEG2000 encoding. In order to demonstrate the practicability of the framework, a JPEG2000 encoder LSI has been implemented by using 0.18 mu m CMOS technology, which consists of two hardware modules and a configurable processor. This paper also describes real-time human object extraction algorithm, which call be used for video phone. Software simulation result of face and hair object extraction with the use of XScale processor claims that QCIF 15fps video call be processed in real-time.
