基于小波域的数字水印程序，希望对大家有帮助(Digital watermarking process based on DWT)

利用粒子群优化算法来求解PID参数的一个好例子(get PID parameters based on PSO)

说明：  人脸检测代码,可对人脸进行分割,识别出人脸区域,表识出来,速度也很快 (Face detection code, may be divided on the human face, identified face region, the table know it, the speed quickly)

说明：  这是一个关于小波阈值图像去噪的程序，通过对分解后的系数各层进行不同的阈值处理，最后得到去噪后图像。(It s about a wavelet threshold program well worth beginners reference! )

本例是使用kalman filter作为状态观测器，对直流无刷电机的状态进行观测。从结果可以看出，对状态估计的效果非常的好(This example is the use of kalman filter as an observer state, the state of brushless DC motors were observed. As can be seen the results of state estimation of the effect is very good)

张正友标定的matlab源程序，包括详尽的测试程序和函数程序。师兄留下来，瑰宝啊！！(Zhang Zhengyou matlab calibration source, including detailed test procedures and function procedures. Brothers to stay, treasure ah! !)

3点法计算数值微分，你可以试试看，3dianfa jisuan shuzhiweifen (calculate the numerical differentiation using the three point method)
