数字图像处理，颜色模型，对图像进行颜色转换(Given a color image ‘football.jpg’. 1) Display the three component images: red, green and blue. 2) Perform histogram equalization for the original image in RGB color space, and display the result. 3) Convert RGB to HSV, equalize just V component of HSV image, convert the processing result back to RGB, and then display it. 4) Discuss and compare these results. )

Gaussian映射的Lyapunov指数，MATLAB，非线性动力学(Gaussian map Lyapunov exponents，MATLAB，nonlinear dynamics)

维纳滤波语音增强算法:语音增强算法的维纳滤波器，通过scalart 1996提出的实现。使用一个决策指导的方法跟踪的先验信噪比。请注意，该信号的第一0.25sec用于模型的噪声，即，它是假定的演讲之后，0.25sec开始(Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec)

对于matlab入门的学习有着很大的帮助，附有很多的例题来帮助初学者理解。(Matlab entry to the study of great help with a lot of examples to help beginners understand.)

求解陀螺仪的姿态角，采用四元素的四阶龙格库塔法求解，含姿态初始四元素的确定。(Solving gyro attitude angle, using the four elements of the fourth-order Runge-Kutta method to solve, including the initial four elements determined attitude.)

说明：  主要是用于提取超声导波的时域特征，例如偏度参数、峰度系数、形状系数、离散系数等等(Time Domain Characteristics for Extracting Ultrasound Guided Waves)
