Abstract
This paper presents the novel design of an avatar-based personal messenger called the AvPM. Differing a lot from the common messengers like Microsoft MSN and Yahoo Messenger, the proposed AvPM allows the receiving site to synthesize on the fly a virtual avatar having the synchronized voices, facial expressions and head poses of the speaker at the speaking site. More importantly, the visual data transmitted by the AvPM is not a large volume of compressed video of the speaker’s appearance, but a small amount of synthesizing parameters for rendering the synchronized avatar’s appearance. This novel feature makes the AvPM very suitable for personal audio-visual communication over low-bandwidth networks. The experimental results show that the AvPM outperforms the MSN and H.264 in terms of the required network bandwidth and the rendered audio-visual quality.
