Abstract

DCT transform and SPECK algorithm are combined in this paper. A DCT-based approach to progressive image coding is proposed

which has the characteristic of simplicity and can achieve high compression using zerotree coding method.The output stream is embedded

which is easy to control rate

and error resilient.The algorithm has low computational complexity so it is suitable for image coding and transmission with low complexity.
