灰色预测，求关联度、极差、关联系数以及后验差检验(Gray predicts that demand correlation, poor, poor correlation coefficients and posterior test)

基于到达时间差(ToA)的非线性最小二乘(NLS)定位方法(Based on Time Difference of Arrival (ToA) nonlinear least squares (NLS) positioning method)

1.灰度变换：选择一幅对比度不足的图像，对该图像进行灰度变换,增强对比度，显示增强前、后的图像以及它们的灰度直方图。 2.直方图均衡：选择一幅灰度直方图不均匀的图像，对该图像进行直方图均衡处理，显示处理前、后的图像以及它们的灰度直方图。 3.选择一幅边缘较模糊的图像，利用高通滤波器（选择或自己设计）对该图像进行边缘增强，观察增强的效果。 4.选择一幅图像，叠加零均值高斯噪声，分别利用低通滤波器、维纳滤波器和中值滤波器对该有噪图像进行滤波，显示滤波后的图 像，比较各滤波器的滤波效果。 5.选择一幅图像，叠加椒盐噪声，分别利用低通滤波器、中值滤波器对该有噪图像进行滤波，显示滤波后的图像，比较各滤波器的 滤波效果。 (err)

Matlab的数值拟合和插值方法介绍，内有程序说明和算法介绍。主要对最小二乘，线性回归作了介绍(Matlab Numerical fitting and interpolation methods introduce, within the description of the procedures and algorithms have introduction. Mainly on the least-squares, linear regression was introduced by)

说明：  最优化算法，使用Q型惩罚因子，在matlab环境下运行的通用算法。(Optimization algorithm, the use of Q-factor penalties, in the matlab environment running under a common algorithm.)
