In this paper

we proposed a fractal characters based method for nature environment image segmentation. The main goal of the segmentation is to find the artifact object from the image. Based on several kinds of fractal characters

we can acquire the description of roughness of each part of the image. Then we can get the segmentation of the image. We also analysis the performance of the data fitting in the box dimension estimation

and present an optimizedmethod. According to a lot of experiments

the proposed approach is proved to be suitable for texture segmentation and artifact object finding in natural environment images.
