在天文图像远程网络观测分析探讨的基础上，提出了一种适合远程网络观测技术的解决方案，同时给出关键算法及测试结果。该算法可以实现有损和无损压缩、感兴趣区域压缩，并能根据网络带宽的波动及时调整压缩率，将天文图像的有效信息及时传给远程观测者。远程观测者根据网络带宽接收图像码流进行选择性解码，把信息反馈给观测设备进行适当的调整或继续进行目标的观测。 |

Based on analyzing relevant astronomical images, we propose a suitable technological solution for remote network observation. We also give out the algorithm and the test result of it. The algorithm can achieve image compression with or without information loss, as well as compression of specific interesting image regions. According to the fluctuations in network bandwidth the algorithm timely adjusts the compression rate. The astronomical image information will be effectively transmitted for remote observation in time. The remote observation can receive image bit-stream according to network bandwidth. The remote observation can further carry out selective decoding, and feed the information back to the observational instruments to make appropriate adjustments, or to continue observing objects. |
