coding for color feature extraction

A matlab program that illustrates the occurance of aliasing in a digital signal. if the sampling frequency is not sufficient then aliasing occurs.

本程序基于MATLAB编写，用于加密一幅彩色图像，通过将图像分解为RGB三通道，并且用颜色索引发完成图像的加密，程序中包含了解谜代码(The program based on MATLAB, is used to encrypt a color image, through the image is decomposed into RGB three-channel, and complete the image encryption with color hair, understand the enigma code were included in the program)

Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two improved Watterson models and Pseudo- Deterministic model. As a deterministic model, Volger model basically describes the characteristics of HF wideband channel, but it also needs to be improved. The improvement of Vogler model is given in this paper.
