The natural multi-fractal spectrum was computed and analyzed with the multi-fractal method.The parameters of multi-fractal spectrum were used to describe hierarchically refined structure of terrain and highlight the singularity characters of local area.Thus,the exact characterization of trrain surfaces is obtained.Combined with image processing and analysis technology,the satellite photo of the snow-covered Himalayas collected by NASA was processed.And by computing the multifractal spectrum,two characterist...
