Abstract: A method of computation for multi-window local fractal feature is presented，a novel segmentation algorithm based on the method and traditional image segmentation algorithm is proposed to deal with target under complex environment.Firstly，exponential wavelet at one scale is used to filter image in order to reinforce the edge of image.Secondly，it exacts the fractal intercept of original image using multi-window approach according to the intensity of filtered image，and realizes target detection using region growing algorithm.Finally，morphological operation is utilized to extract target.Experiments show that the proposed method can segment and extract the area of target under complex environment effectively and its low calculation is also proved.
