对模拟信号抽样，然后进行离散傅里叶变换，利用自编DFT函数，得到频谱，然后进行频谱的还原。(Sampling the analog signal, then the discrete Fourier transform, DFT self function obtained spectrum and the spectrum reduction.)

用Matlab对经过与处理后的车牌图像进行分割的程序，可以很好的分割车牌，把各个车牌字符都分割出来(Matlab right after dealing with the license plate image segmentation procedures, can good segmentation plates, license plate characters are all split up)

对图像进行自适应中值滤波，消除噪声的影响(Adaptive median filter to eliminate noise on the image)

求解无约束最优化问题的方法之一：拟牛顿法(Quasi-Newton Method)

说明：  数值分析 隐式算法改显示算法 非弹性分析(Numerical analysis implicit algorithm to display the elastic analysis algorithm)

产生不同频率、不同幅度的两种正弦波信号 对两个信号进行叠加并做频谱分析 还原原来两个信号（LPF)(Produce different frequency, the two sine wave signals of different magnitudes of the two signals are superimposed and do spectral analysis to restore the original two signals (LPF))

计算香浓熵，用于信号处理，表征信号混乱度。试过了，可以正常使用(Shannon entropy is calculated for signal processing and signal confusion is calculated. Tried, can be used normally)

对正弦信号进行傅里叶变换，并对比不同的信号长度与采样频率对结果的影响(Fourier transform of the sinusoidal signal and contrast the different length of the signal with the sampling frequency results)
