Open Access Remote Sensing Classification Using Fractal Dimensions over a Subtropical Hilly Region

Subtropical hilly regions in China have various and complex surface features, which are difficult to identify in remote-sensing images. A new algorithm for calculating the fractal dimension of a single pixel of a remote-sensing image is presented. The fractal dimension data for a scene captured in an ETM+ (i.e., Enhanced Thematic Mapper Plus) image were used to compose a new image together with the second and fourth bands of the ETM+ image. Using the new image, the land-use/land-cover types and forest categories in the region were identified using a maximum likelihood classification. The accuracy assessment of the classification gave an overall accuracy of 80.69 percent and a Khat value of 0.78. The proposed method is a little more accurate than the method that does not use fractal dimension data, especially for identification of different types of vegetation in the region.
