B = COLORSPACE(S,A) converts the color representation of image A
where S is a string specifying the conversion. S tells the
source and destination color spaces, S = dest<-src , or
alternatively, S = src->dest . Supported color spaces are

Description: Lab2RGB takes L, a, and b double matrices, or an M x N x 3 double
image, and returns an image in the RGB color space. Values for L are in
the range [0,100] while a* and b* are roughly in the range [-110,110].
If 3 outputs are specified, the values will be returned as doubles in the
range [0,1], otherwise the values will be uint8s in the range [0,255].
This transform is based on ITU-R Recommendation BT.709 using the D65
white point reference. The error in transforming RGB -> Lab -> RGB is
approximately 10^-5.

Description: 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.
