Abstract: In view of the existing different image segmentation methods，this paper uses a partial image segmentation method based on the multi-fractal Hölder exponents and the multi-fractal singular spectrum，the method can maintain and strengthen the image of local features，and extract some interested sense of image.Experiments show that this method achieves a better division，and gets an ideal image of segmentation results.

Key words: multi-fractal theory, Hö, lder exponents, multi-spectral singular spectrum, image local segmentation

摘要： 在现有对图像分割方法研究的基础上，采用基于多重分形的Hölder指数和多重分形奇异谱联合考虑的图像局部分割方法。方法具有保持和加强图像局部特征，对图像中某些敏感部分进行边缘提取，较好实现图像分割的功能。实验表明该方法能够达到较好的图像分割效果，具有实时性、有效性和可实现性。
