摘要
Abstract
In recent years, with the further development of remote sensing technology and geology, more and more scholars have tried to use remote sensing data to enhance the lithologic information in-depth study. However, in thick vegetation areas, Limited rocky outcrops and weak stratigraphic visibility make it difficult to directly ex-tract and analyze information in remote sensing image, and therefore it is a challenge for traditional processing methods. Starting from the optical remote sensing images of the spatial domain reflection band, and choosing four sub images, such as the monzonitic granite of Bengbu Tushan and Dabie Mountain and the shales in the Manmao Formation of the kiln of Cambrian system in Huainan Province and that of Fengyang Jiushan, as the research ob-ject, this paper transforms the remote sensing image to the frequency space by using Fourier transformation, to ob-tain the energy distribution of spectrum to determine the threshold of the fractal filter. We apply different filters on the frequency domain with the help of these thresholds. Finally we transform it into spatial domain in order to sepa-rate anomaly and background and to improve the lithologic information of remote sensing image.关键词
