| 摘 要： | 提出一种基于SPIHT算法编码结构的小波树图像的概念,从图像小波变换系数图中提取出各小波树,然后对各小波树、各比特平面层的编码数据独立打包,按重要性依次发送,来提高整个码流的鲁棒性。实验表明,本算法是相当有效的,即使在很高的丢包率情况下,仍能提供较好的解码图像并保留了它的渐进显示特性。

| Abstract: | In this paper,we propose an algorith m to reorganize the wavelet transform coefficients ac-cording to wavelet tree concept and c ode each wavelet tree independently.Then,each coded bit -plane of each wavelet tree is packetized and t ransmitted to networks independent ly with little header information.Ex-perimental results show that the pro posed algorithm improves the robustness of the bit steam while preserv-ing its progressive display properties. |
