Abstract :
This paper presents a full compression decompression algorithm for a distributed videoconference system via the Internet. It is based on a new method called LAR. This algorithm mixes both spatial and spectral approaches. The spatial coder provides a low resolution image but preserves object boundaries, whereas the spectral coder can add local texture information. The encoding scheme is progressive, providing great flexibility for rate/quality trade-offs
