报告摘要：

Multifractal is a new branch of nonlinear science research, which has been widely used in various disciplines. In the analysis of time series, especially in the study of financial market, multifractal claims that the capital market has significant fractal structure, sharp-peak and fat-tail characteristics, and the series has persistence or anti-persistence within a certain scale. Furthermore, there are also applications in bioinformatics, air pollutants, turbulent wind speed measurement and other issues. In image processing, it can be used for edge detection and segmentation. In addition, in our recent research, we have realized the classification of brain MRIs by using the multifractal spectrums.
