使用MATLAB，实现以下四个功能 一、获取图片RGB值：给定一张图片，获取点(x,y)，以及(x,y)周围8个点的R、G、B值。 二、实现rgb2gray函数：使用matlab实现rgb2gray的功能，并能计算出转换后灰度图片的方差。 三、灰度图对比度增强：分别使用灰度拉伸和直方图均衡化，增强给定图的对比度。 四、图像去噪：对给定图片加椒盐噪声，并选择两个去噪算法去除椒盐噪声。 (Using MATLAB, to achieve the following four functions First, access to image RGB value: Given a picture, get the point (x, y), and (x, y) around 8 o clock in the R, G, B values. Second, the realization rgb2gray function: using matlab realize rgb2gray functions, and can calculate the variance after the conversion of grayscale image. Third, the grayscale contrast enhancement: namely, the use of gray stretch and histogram equalization, contrast enhancement given graph. Fourth, the image denoising: for a given image add salt and pepper noise, and you know at least two denoising algorithm to remove salt and pepper noise. )

可以通过CC 方法进行相空间重构，计算嵌入维数和延迟时间，在此基础上，对单音素语音进行递归图和递归定量分析。(The CC method can be used to reconstruct the phase space and calculate the embedding dimension and the delay time. On this basis, the monosyllabic speech is recursively and recursively analyzed.)

数据处理及误差分析采用了matlab软件来实现，它的界面虽然没有VB等直观简便，但其可调用的函数多，实现起来比较方便，程序中已经实现的功能有： （1）求算术平均值； （2）求残余误差（绝对误差）； （3）求标准差； （4）判断粗大误差，如果发现粗大误差,剔除粗大误差后再进行计算； （5）判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)

说明：  matlab数值编程使得数值计算工作量大大减轻，但是由于它其实是一种解释语言，而且没有国际标准，另外也没法在没有安装matlab的计算机上运行，不能用于计算密集型应用场合，极大地限制了它地应用，主要应用于物理，数学和化学，部分工程应用领域的计算工作量小的科技工作者。计算工作量大的工作，如流体力学求解，虽然matlab有解偏微分方程组的方法，但那几乎是用来作为例子来说明的，换句话说，只能作为上课例子。大型流体力学计算是计算密集型的一个例子，需要高效运算程序或并行化处理。 (chao liu ji suan)

该代码实现了以2为因子的图像升采样和降采样功能。 降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。 升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。 降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和四个结果图片。 图片1.原始图片。 图片2.平滑滤波器降采样&像素点直接复制升采样。 图片3.平滑滤波器降采样&线性插值升采样。 图片4.不使用平滑滤波器降采样&像素点直接复制升采样。 图片5.不使用平滑滤波器降采样&线性插值升采样。 (The code to achieve a 2-factor image upsampling and downsampling function.
