RMatlab
To call R from within Matlab, you will need to have R compiled as a
shared library. This needs to be done when compiling R from source
(or via one of the binary distributions that have support for this.)
Download the R source from cran.r-project.org.

数字图像处理1
说明: 任务 1 编写以两幅灰度图像为输入的 MATLAB 函数,计算下列图像差值度量:均方误
差(MSE)信噪比(SNR)峰值信噪比(PSNR)均值绝对误差(MAE)处理给定的测试图像“Lena”及其原始和后添加噪声形式。
任务 2 编写 MATLAB 函数,通过两种不同的方法将一幅灰度图像从原始大小下采样到
给定输出大小:a)直接消除像素,b)在消除像素之前进行初步图像平滑处理。用缩放系数 2:1、4:1、8:1 和 16:1 对给定的测试图像“Living.”进行处理。
任务 3 编写 MATLAB 函数,通过两种不同的方法将灰度图像从原始大小缩放到给定的
输出大小:a)像素重复使用上述方法将任务 2 中处理的图像缩放回原始大小。使用为任务 1 编写的 MATLAB 方法计算原始图像和缩放图像的 MSE 和 PSNR。将 MSE和 PSNR 分别作为大小缩减率的函数。定义对于相同的尺寸缩小比,收缩/缩放方法的组合提供最小 MSE 和最大 PSNR。
任务 5 编写 MATLAB 函数分别对测试图像“Fig0316(1)(top_.)”和“Fig0316(4)(._.)”执行直方图均衡。显示直方图均衡前后直方图的直方图。(task1

I am uploading a file of Direct Sequence and Frequency Hopping Spread Spectrum Systems,
understanding differences between both schemes.
Plz accept it.
Thanks and Regards,
