DCT-Based Approach to Progressive Image Coding
Qing Zhu · Dianzi xuebao · 2002
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 bit 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.
