提取图像sift特征，并且showkey函数在图像上直观的显示出来(Sift extracted image features, and showkey function in the image displayed on the intuitive)

说明：  一个4阶的切比雪夫Ⅰ型低通滤波器，可以用它对信号进行滤波。当然，滤波器的零极点图也是必不可少的。(A 4-order Chebyshev low-pass filter of type Ⅰ, you can use it to filter the signal. Of course, the filter pole-zero map is essential.)

A COM based interface that allows you to call R functions from within MATLAB. The functions are: openR - Connect to an R server process. evalR - Run an R command. getRdata - Copies an R variable to MATLAB. putRdata - Copies MATLAB data to an R variable. closeR - Close connection to R server process. Rdemo - An example of using R from withing MATLAB.

The objective is to demonstrate character/ symbol frequency distribution analysis (reference to the English language) on 2 vintage ciphers, namely Caesar cipher (a mono-alphabetic substitution cipher) and the Vigenere cipher (a poly-alphabetic substitution cipher).
