The multimedia applications in a multiresolution environment

such as progressive transmission of image

image database browsing

etc.

arise scalable image coding algorithm. This paper first explains the concepts of all kinds of scalable image coding

and gives an analyse for the scalable image coding algorithms in JPEG and JPEG-2000. Secondly

an overview of major methods already used or under investigation for scalable image coding based on Wavelet

DCT and Matching Pursuit with the scalable coding tools and methods is introduced

and the decoder performance comparison among the three kinds of scalable coding is given. In addition

the trend of the three kinds of scalable coding and their extension in video scalable coding is discussed. Finally

the future development of image coding is also analyzed and conjectured in the paper.
