A Study On Rock Information Enhancement Of Remote Sensing Image By Multi-Fractal Filter Method
نویسندگان
چکیده
A remote sensing image is composed of vegetation and base rock or soil in moutain areas, which can be decomposed by the fractal model through Fourier transformation to enhance base rock or soil information. In this paper, four scene images of two types of bed rock from Anhui province are taken as a case to demonstrate the method’s validity: two scene images’ base rocks are monzonite granite while the other two base rock are limestone and mudstone. The fractal spectrum of the four scene images can’t be distinguished without processing yet the result shows good contrast for the two types of rock. Other contrasts between original and processed images show obvious difference in the two types of image such as in 2D-scatter map, in composed color map. The result proves that the method can improve base rock information in those vegetation covering region.
