Wavelet Transform in Remote Sensing Image Compression of the Key Technical Analysis

摘要

To solve the algorithm in the image compression of remote sensing than complex, efficiency lower etc. problem, this paper has put forward a kind of fast, efficient image compressed algorithm on the foundation of little wave coding. Firstly, have gone on for the aspects such as the image compressed coding method, kind and performance appraisement of remote sensing have been further elaborated. Then the coding based on wavelet transform has been described in detail. Finally crucial technology for the image compressed algorithm of remote sensing has carried out thorough research. Experiment result shows: The PSNR value of the image compressed algorithm of remote sensing that this paper adopts has got great advance than traditional algorithm.
