The Study of the Application of Image Compression Based on Wavelet Transformation in Astronomical Remote Observation

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.
