matlab 检测时频分布中的正弦曲线，C编写，可用matlab调用(matlab sine curve in the frequency distribution of detection, C preparation, available matlab call)

分别在2幅灰度图像中加入一定量的高斯噪声和椒盐噪声，噪声强度自定。然后采用3×3的均值滤波器和3×3中值滤波器分别对噪声图像进行处理，给出两种处理方法的峰值信噪比(PSNR)；仿效“中值滤波”的方法，对原图像分别进行“极大值滤波”和“极小值滤波”，对所形成的图像给出说明。(Two gray-scale images a certain amount of Gaussian noise and salt and pepper noise , noise intensity since .)

matlab/simulink环境下仿真的异步电动机矢量控制，运行良好，基础系统，可供初学(matlab/simulink environment simulation of induction motor vector control, runs well, base system, for beginners)

语音增强结果评价框架，其中包括四种语音质量评价方法：信噪比SNR，分段信噪比segSNR，对数谱失真LSD，PESQ。还包括生成设定信噪比语音文件的m文件。也适用于其他领域的语音质量评价。(The speech enhancement results evaluation framework, including the four speech quality assessment method: the SNR signal to noise ratio, segment the SNR segSNR, and the number of spectral distortion of LSD, the PESQ. Also includes the generation of m-files to set the signal to noise ratio voice files. Also applies to other areas of speech quality assessment.)

模拟退火的matlab实现程序，含原始的输入数据，即各个城市的具体坐标。(Simulated annealing to achieve the matlab program, including the original input data, namely the specific coordinates of each city.)

自适应（LMS）算法在噪声抑制中的应用。在仿真中，原始信号选为sin((0.2*pi)*t), 噪声信号采用标准白噪声，延迟D=1，收敛因子分别是u=0.001和u=0.3(Adaptive (LMS) algorithm in noise suppression application. In the simulation, the original signal is selected sin ((0.2* pi)* t), noise signal using the standard white noise, the delay D = 1, respectively, convergence factor u = 0.001 and u = 0.3)

说明：  BP分类算法，实现多分类的任务，准确率高，耗时少(BP classification algorithm can realize multi-classification task with high accuracy and less time consuming|.)
