Description: 提出一种基于分形理论和BP 神经网络的航空遥感图像有监督分类方法。该方法尝试将航空图像
的光谱信息和纹理特征相结合。它首先将彩色航空图像由RGB 格式转化为HSI 格式,然后,根据亮度计算分
数维、多重分形广义维数谱q-D( q) 和“空隙”等基于分形的纹理特征,同时加入归一化的色度和饱和度作为光
谱特征,采用BP 神经网络作为分类器。通过对彩色航空图像的分类实验,结果证实该方法行之有效。-Based on fractal theory and BP neural network of aviation remote sensing image supervised classification method. This method tries to aerial images of the spectral information and texture characteristics of the combination. It will first color aerial images from the RGB format into HSI format, and then, according to the brightness calculation of fractal dimension, the generalized multi-fractal dimension spectrum qD (q) and the Platform: |

Description: Charles Li Multifractal1.0工具箱用于计算股价数据的多层分型谱。
目前主函数为MultifractalRE，用于计算某一天的多层分形谱。
MulDataGenerator和MulGetdate主要用于生成函数所需格式的数据。
TData1.mat中保存的是沪深300 五分钟数据。
Script_MultifractalRE是调用脚本。具体使用说明见每个函数-Charles Li Multifractal1.0 Toolbox data used to calculate the price of many sub-type spectrum. Currently the main function of MultifractalRE, used to calculate a multi-day fractal spectrum. MulDataGenerator and MulGetdate mainly used to generate the required data format function. TData1.mat CSI 300 is stored in five minutes of data. Script_MultifractalRE is calling script. See detailed instructions for use of each function Platform: |

明奇异指数和相应的谱函数作为多重分形谱的重要参数,一定程度上反映了股指本身的变化范围
和高低价位出现频率的变化,然而谱函数可以预测股市趋势的断言在沪市并不成立。
关键词:统计物理 高频数据 多重分形谱 奇异指数-This paper studies the multifractal statistical physics methods, the Shanghai Composite Index more than four years of high frequency data for the study of one minute
Object, calculated multifractal spectrum and characteristic parameters of the actual transaction data, and determine the weighting factor ranges. Results Table
Ming singularity index and the corresponding spectral function as a multi-fractal spectrum of important parameters, to some extent, reflect the range of variation of the index itself
And the level of price changes in the frequency of appearance, but the spectral function can predict stock market trends assertion does not hold in the Shanghai stock market.
