This paper describes our work of using Wavelet Transformation to compress and encode images in order to appropriateley support image data handling in mobile systems. The paper at first introduces the motivation and our basic idea of supporting the efficiency and adaptivity at the representation level. In Section 2, the identified requirements on the coding schemata are given which guide the selection of an appropriate transformation method i the image coding schemata. In section 3, Wavelet Transformation and its advantages for image handling are discussed. The prototype of an adaptive image service is presented in Section 4. In this section, it will also be discussed how various levels of adaptivities can be achieved. Finally, conclusio is made based on the comparison with related works.
