Simple demo of sift from mr Lowe

人脸定位，滤波，定位，分割等一系列的实现，里面有详细的文字说明和注释(face detection，dingwei,fenge)

说明：  这是一个改进了的模糊聚类算法程序，请放心下载，已调试过(This is an improved fuzzy clustering algorithm program, please rest assured that download has been debugged)

使用matlab中的GUI设计的译码器，配有适当的注释，适合初学者。(The GUI design using matlab decoder, with appropriate comments, suitable for beginners.)

对蓄电池采用低压配电网 P/V 和 Q/f 下垂控制策略 ， 实现从并网运行到孤岛模式的切 换 。 考虑实际风速和光照强度的变化 ， 对风能与光伏混合微电网在并网和孤岛 2 种模式中的运行特性进行 仿真分析 ， 验证控制方式的可行性(The realization of the operation the grid to the island change . Considering the actual wind speed and light intensity , Hybrid grid for wind energy and photovoltaic grid connected and isolated Two The operating characteristics of the Simulation analysis , Verify the feasibility of control mode)

说明：  对信号进行短时傅里叶变换和小波变换，观察其时频特性，压缩包中含有需要用到的测试信号文件，可以直接运行，供参考(Carry out short-time Fourier transform and wavelet transform on the signal, observe its time-frequency characteristics, and the compression package contains the test signal files needed, which can be directly operated for reference)
