摘要:为提高密码的抗攻击性,利用超混沌系统随机性好!可确定再生,且密钥空间较大的特性,提出了一种基于四维连续超混沌系统和扩展映射的实时视频流加密算法"(Abstract: In order to improve the password anti-aggressive use of system randomness hyperchaos good! Regeneration can be identified, and key characteristics of the larger space, a row based on four-dimensional hyperchaotic system and expansion of mapping real-time video stream encryption algorithm )

MATLAB is a software package for doing numerical computation. It was originally designed for solving linear algebra type problems using matrices. It’s name is derived from MATrix LABoratory.

说明：  变分模态分解算法是2014年新提出的，广泛应用于信号处理领域。 VMD分解的子程序，给定分解的时域信号，数据保真约束平衡参数、噪声波峰时间步长、VMD分解个数、迭代精度可以得到 分解的子分量、子分量的波谱、各模式的中心频率。(The variational mode decomposition (VMD) algorithm was proposed in 2014, which is widely used in the field of signal processing. Given the time domain signal decomposed by VMD, the data fidelity constraint balance parameter, the time step of noise peak, the number of VMD decomposition and the iteration accuracy, the decomposed sub components, the spectrum of sub components and the center frequency of each mode can be obtained.)

利用离散余弦变换求取重力或磁异常的水平与垂直导数，简单实用。(using the DCT transform to calculate the horizontal and vertical derivatives of potential-field anomaly.)

数字图像频域滤波处理，分别进行二阶巴特沃斯(Butterworth)高通、低通滤波器。(Digital image processing frequency domain filtering, respectively second-order Butterworth (Butterworth) high pass, low pass filter.)

此Matlab程序中包含两种定位算法，一种为最小二乘法，另一种为加权最小二乘法。(This Matlab program contains two location algorithm, a least-squares method, the other is weighted least squares method.)

web服务选择优化算法，采用单纯性改进算法来实现。效率优于matlab原始库函数。(web service selection algorithm, improved algorithm using simple to achieve. Efficient than the original matlab library function.)
