摘要：
This paper outlines our project on image coding for mobile wireless environments. The mobile, or even portable, system has a limited computation power, but deals with a large quantity of image data and a public-accessible transmission task. Thus the system must be simple, and perform compression and encryption at the same time. We investigate hierarchical data structures and related algorithms. The preliminary results, both theoretical and experimental, are encouraging. (C) 1997 Elsevier Science B.V.
