Abstract :
Embedded system architecture which can 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 on the ability of exploring implementation scheme for each process of JPEG2000 encoding. In order lo demonstrates the practicability of the framework, a JPEG2000 encoder LSI has been implemented by using 0.1 8μm CMOS technology, which consists of two hardware modules and a configurable processor. This paper also describes real-time human object extraction algorithm, which can 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 can be processed in real-time.
