摘要
Abstract
A new approach for water information of Miyun Reservoir to feature extraction based on multi-scale fractal signature of ETM + remote sensing image was introduced. Firstly,the blanket method was used for computing fractal dimension of each pixel,and water information corresponding scale was analyzed. Secondly, the fourth down fractal signature was to extract water information. Accuracy assessment for water information was done based on extraction results of water index and extraction accuracy was as high as 98.12%. The result showed that this method can effectively extract water information,and provided a reference method for future related research.关键词
