image quality measures

说明：  独立成分分析算法降低原始数据噪声，并提取特征值，非常有用得数据去噪程序。(Independent component analysis algorithm reduces the raw data noise, and extract characteristic value, is more helpful data denoising procedure.)

应用Matlab采用Galerkin法求解偏微分方程(Galerkin method for solving partial differential equations by matlab)

说明：  本程序实现了粒子滤波基本算法。matlab代码。(failed to translate)

解决了三维数据可视化的问题；在三维网格点上数据绘制显示它的大小。 通过z轴坐标点更容易区分边缘颜色变化。可以通过设置线宽参数该选项设置为0。(This function solves the problem of visualization of 3 dimensional data in one plot(plot3). Data is plotted on a 3 dimensional mesh with point size showing value of it. Edge color changes via z axis to distinguish coordinate of points easier. That option can be turned off by setting the linewidth parameter to 0. )

说明：  加速度到位置的二次积分模型，采用simulink编写，带加速度噪声，可用于简单的导航位置与实际位置仿真(Acceleration to the position of the double integration model, using simulink writing, with acceleration noise can be used for simple simulation of the actual location of the navigation position)

温度模型 需要的可以直接拿走 但是没有说明(Temperature model may need to take but did not say directly)

基本粒子群算法的matlab源程序，适合于初学者学习的模板。(Matlab source of the particle swarm algorithm, suitable for beginners to learn the template.)

语音信号的时域分析，有短时能量，短时平均幅度，短时过零率，清音自相关序列，浊音自相关序列，傅里叶分析。(Speech signal time-domain analysis, short-time energy, short-term average, short-term zero-crossing rate, voiceless autocorrelation sequence, voiced autocorrelation sequence, Fourier analysis.)

本程序可将输入的RGB图像转化为灰度图像！在Matlab环境下编程实现。(this procedure can be imported RGB images into gray image! Matlab programming environment.)
