Progressive coding, another feature of the JPEG 2000 standard, means that the bit stream can be coded in such a way as to contain less-detailed information at the beginning of the stream and more detailed information as the stream progresses. This makes it ideal for Internet/network applications―especially with large images and low bandwidths―as the image can be seen instantly on the decoding side, even with low-speed networks or image databases. The lower subbands are shown first, and more detail is added as time progresses. The picture thus becomes sharper and more detailed over time, and the entire image does not have to be downloaded before it can be seen

无线传感器网络自组织成簇问题优化模型 为了有效延长网络的运行时间，需要设计能量最优的自组织成簇机制，以适应传感器网络的特点。本文提出了一种适合无线传感器网络的能量有效的成簇优化模型。-Self-organizing wireless sensor network problems optimization model cluster in order to effectively extend the network run-time, the energy necessary to design the optimal mechanism for self-organizing clusters, in order to adapt to the characteristics of sensor networks. This paper presents a wireless sensor networks for energy efficient cluster optimization model.
