matlab下使用penalty策略确定降噪的阈值(matlab use penalty strategy to determine the threshold denoising)

跳频（占空比为0.1）4fsk的部分频带干扰误码率计算，这个程序是基于matlab的，自己编的，呵呵(Frequency Hopping (duty cycle 0.1) 4fsk the partial band interference bit error rate, this procedure is based on matlab, and their series, Oh)

this code is LSB data hiding source book.

matlab code 使用dibr 產生虛擬圖，使用實裡面有 readme，code 裡有說明如何使用。(dibr Matlab code to generate the virtual image, the use of solid inside the readme code, there are instructions how to use.)

时域序列x 和 h 的N点循环卷积子程序，用于matlab仿真调用(Time domain sequence x and h N-point circular convolution subroutines for the call of matlab simulation)

Gardner算法的Matlab仿真与实现(simulation and implementation of Gardner algorithm)

自适应子空间辨识，通过输入输出数据，计算状态空间方程，建模并预测。(Adaptive subspace identification, through input and output data, calculates the state space equation, modeling and forecasting.)

说明：  基于Matlab的扩频高度表捕获跟踪算法软件仿真(Matlab-based spread-spectrum acquisition and tracking algorithm for software simulation altimeter)

该程序是用matlab写的一个利用遗传算法的选择性集成算法(The program is written in a matlab genetic algorithm using selective Ensemble Learning algorithm)

A image with bad contrast is hard to be segmented. So this function analysis the RGB chennel, find the worse distributed chennel and fix it , then the result is a normal contrast image
