As we rolling into an information super-highway era, progressive data transmission and compression is crucial in digital image telecommunication. Recently, RSSIPL has developed such a technique, called Multistage Predictive Coding (MPC) which can decompose a signal into multiple stages as well as reconstruct the original signal based on decomposed signals. In particular, the technique can be used for image transmission such as PACS (Picture Archiving and Communication Systems) currently being used in many hospitals and medical centers. Thus far, MPC has shown to be a promising technique in signal and image processing. In addition, RSSIPL currently collaborates with the Taichung Veterans General Hospital in Taiwan, Republic of China to develop the first Picture Archiving and Communication Systems (PACS) in Taiwan. A tele-mammography consultation pilot system was also recently developed for telemedicine. Presently, Dr. Chang is on the editorial board of the Journal of High Speed Networks in charge of the area in image and video communications and was also the guest editor of a special issue of that journal on Telemedicine and Applications, the first issue, April 2000.
