Although motion compensation is a key element of the MPEG algorithm,, it is too computationally intensive to be used in real time video compensation by software. A novel progressive coding algorithm is therefore developed for a low cost personal video communications system to real-time video transmission via the Internet. The codec gives good performance over range of peak bitrates from 0.1 bpp to 1 bpp. Over the whole range, the quality of the reconstructed sequence is significantly better than "motion JPEG," while the codec is much simpler and faster than MPEG. Wavelet representation is a powerful processing technique that provides a multiresolution decomposition of images. The coding schemes for HDTV and video phone based on wavelet decomposition will also be presented. BIOGRAPHY Huijuan Li attended Zhejiang University in China. She received her BS Degree in Electrical Engineering in 1985,, her MS Degree in 11988 in Communications and Electronic Systems and her Ph.D. in 1993 writing her dissertation on "Image Compression adn Coding and Filters." She had a post-Doctoral Fellowship at the Chonbuk National University in South Korea form July 1994 - July 1996. From February 1996 to January 1997, she was on the research staff at Bath University in England studying the Development of personal video communications system by Software only solution of real-time video transmission via the Internet. She is currently working at Wriight State University.
