【Abstract】 Considering the importance of remote sensing image and the merit of wavelet encoding method,the authors propose a remote sensing image encoding method that can ensure surveying precision.The authors studied the statistical character of every sub-image under the different filter length after wavelet analyzing,and drew some useful conclusions.At last,the authors put forward that the best scheme of remote sensing image compression is selecting the four coefficient wavelet filter.更多还原
