光学图像的几何仿真，采用已有的光学图像作为参考，布置在传感器照射范围区域，然后根据卫星轨道、姿态等获得新的图像，该图像能够反映原始图像的几何特性(Optical image geometry simulation, using the existing optical image as a reference, arranged in the area illuminated area of ​ ​ the sensor, then the satellite orbit, attitude and so obtain a new image, the image can reflect the geometric properties of the original image)

产生一维多重分形，以p-model为原理，所得多重分形时间序列具有已知的多重分形谱和奇异性强度。(product fractals)

利用差分盒分形维数的理论得到图像的分形维数的matlab程序(Using differential box fractal dimension theory to get an image of the fractal dimension of the matlab program)

采用结构函数法计算材料界面曲线的分形维数，对应的数据应当为结合界面曲线的.jpg格式，各相关参数的介绍在程序内均有注明。(The fractal dimension of the interface curve of the material interface is calculated by the structural function method. The corresponding data should be in the .jpg format of the interface curve. The relevant parameters are described in the procedure.)

Diffusion-limited  Aggregation（DLA）扩散限制凝聚，是由Witten和Sander于1981年共同提出来的。其基本思想是：首先置一初始粒子作为种子，在远离种子的任意位置随机产生一个粒子使其做无规行走，直至与种子接触，成为集团的一部分。然后再随机产生一个粒子，重复上述过程，这样就可以得到足够大的DLA团簇。(Diffusion-limited Aggregation (DLA) Diffusion Limitation Cohesion was presented by Witten and Sander in 1981. The basic idea is to first set an initial particle as a seed, at any position away the seeds randomly generated a particle to make it random walk until the contact with the seeds, as part of the group. And then randomly generate a particle, repeat the process, so you can get enough large DLA clusters.)

一种分形维数的计算方法，一种分形维数的计算方法(A fractal dimension method, a fractal dimension calculation)

说明：  ATLAS致力于研究以观察为基础的技术从而提供可便携性能。目前它提供c和Fortran77接口。(The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. At present, it provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.)

用迭代函数ifs画分形几何，非常有用，可以仿真画自然界的几何事物(iteration function ,fractal geometry ,ifs)

说明：  Fractal using DCT transform

这是一个一维时间序列关联维数计算程序，用matlab编写，希望对大家有帮助(This is a one-dimensional time series correlation dimension calculation program, using Matlab prepared, and I hope to be helpful)
