数字图像处理，MATLAB语言，RGB转HSI(Digital Image Processing, MATLAB language, RGB to HSI)

录制一段个人自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法和双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a person s own voice signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and the bilinear transform filter design and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback of voice signal Finally, the design of a signal processing system interface.)

Its about cryptography example. useful for chatting with some sort of security

说明：  迭代法 迭代式阈值选取的基本思路是:首先根据图像中物体的灰度分布情况， 选取一个近似阈值作为初始阈值(Iterative threshold selected basic idea is: First, the gray-scale distribution of objects in the image, select an approximate threshold as initial threshold)
