Diag_Rayon_Parabole_Dipole

MATLAB的EMD工具箱，主要是对信号进行IMF分解，然后进行希尔伯特变换。得到信号的瞬时频率，并画出能量图。 使用是解压到matlab的work里面即可。(MATLAB toolbox of EMD, decomposition IMF, then Hilbert transform signal. The instantaneous frequency of the signal, and draw the energy diagram. Use extract to matlab can work inside.)

图像的二维福利叶变换，利用matlab变成实现了二维福利叶变换，代码优化(Fourier transform of the image of two Weifu Li matlab realized with two Weifu Li Fourier Transform code optimization)

求解窗长自适应的短时傅立叶变换最佳窗长算法(Solving long-adaptive window short-time Fourier transform algorithm for the best window length)

说明：  用于快速定位有颜色 背景的车牌， 希望和大家共享，(It is used to locate car plate with color background. I d like to share with all of you.)

人工蜂群算法的源程序，优化效果好，运行时间短。(Artificial colony algorithm source code, optimize the effect is good, operation time is short. )

This is the source code for 2D metrics in gird generation.

说明：  本算法为粒子群优化算法，适用于初学者，压缩包中附带了一个基本函数用于实践。(This algorithm is a particle swarm optimization algorithm, which is suitable for beginners. A basic function is attached to the compression package for practice.)

This is code for segmentation using level set technique.

说明：  针对小流域设计洪水计算中，采用推理公式求解洪峰流量Qm及汇流时间τ的方法繁琐，查算精度较低等问题，提出用牛顿迭代法求解，该方法较原图解试算法收敛快，迭代次数少，计算速度快，精度可靠。计算实例表明，用简单迭代法与牛顿迭代法计算设计洪峰流量，其结果与图解试算法完全一致。()
