Active Contours model(snake)

说明：  希尔伯特黄变换，用EMD将信号分解成本征模态函数，对分解的IMF分量进行hilbert变换(Hilbert Huang transform (HHT), EMD is used to decompose the signal into the cost eigenmode function, and the decomposed IMF component is transformed by Hilbert transform)

彩色噪声图像的curvelet基下的增强，高斯白噪声，显示不仅去噪且增强效果好(Color noise images curvelet based enhancement under the Gaussian white noise, showing not only a good denoising and enhancement)

continuous time sigma-delta modulator modeling

差错控制编码技术是用来提高光纤通信系统质量和可靠性的主要手段。(Error control coding technique is used to improve the quality of optical fiber communication systems and the primary means of reliability.)

计算齿轮啮合刚度的matlab程序，非常有用的，希望大家积极下载(Matlab program for calculating gear mesh stiffness. It is very useful. I hope you can download them actively.)

说明：  电机仿真，MTPA控制策略，永磁同步电机(Motor simulation, MTPA control strategy, permanent magnet synchronous motor)

COMPRESSION OF YTHE IMAGE USING DCT

关于一级倒立摆LQR+PID控制。包含源程序，simulink仿真模型等(On the inverted pendulum LQR+PID control. Including source program, Simulink simulation model, etc.)
