This is a good demo of showing how the mean shift idea works for image pixel clustering

simulink有一个很大的优点是为用户省去了许多重复的代码编写。(simulink have a great advantage for the user save a lot of repetitive coding.)

说明：  多个基于MATLAB约束最优化问题源码。程序具有通用性，供相关人员参考(Number of constrained optimization problems based on MATLAB source code. Process is universal, for future study)

分析了空间矢量永磁同步电机数学模型 建立了永磁同步电机空间矢量控制系统仿真模型 并在MATLAB环境下对变频调速系统进行仿真实现(the space vector PWM controlled PMSM is analyzed the simulation model of space vector PWM controlled PMSM is presented and speed control system is simulated)

本文针对基于经验模态分解ＥＭＤ的时空滤波器存在的固有模态函数分量中频率混叠交叉导致有用信号与噪声一起被滤除的问题结合小波在时间尺度两域表征信号局部特征的特性提出了一种基于能量估计实现ＥＭＤ分解层数确定(In this paper, based on empirical mode decomposition EMD temporal filter mode functions inherent component of cross-frequency aliasing and noise together lead to useful signal is filtered in the time scale of the problem combined with wavelet domain characterization of two local features of the signal characteristics of proposed achieve energy estimation based on EMD decomposition level determined)

说明：  是处理噪声的一个小程序很有用，希望对大家有所帮助(To deal with noise, a small program useful and want to help everyone)
